Beginner Electronics - 4 - Flow + Resistance 

**DISCLAIMER - READ BEFORE WATCHING** I am an electronics hobbyist; I do not have a degree in electrical engineering. This series MAY NOT teach all of the appropriate safety required for general electronics work. Any advice taken from this series should be checked with multiple sources, and a professional should be addressed to ensure proper safety.

I'm almost 10 years late to the video but I'm so thankful I've stumbled across them. The short videos, packed with information that is easy to understand. Thank you!

*summary:* -electrons flowing through a wire is analogous to water flowing through a pipe -pressure drives water flow through a pipe -voltage drives electron flow through a wire -"current" is the rate at which electrons flow past a certain point in the wire -current depends on the voltage and resistance -different material offers different amount of resistance to electron flow

Education on youtube is awesome its just like school but without the bullyin!

Please, continue, when you started with the 8-bit computer thing in ep1 I got so stoked for this series! Really, I know it's hard to continue something that does not get a lot of views, but if I may speak for everyone that does view, please sir, make that 8-bit computer reality!

The water flowing through pipes analogy is probably the best way to explain how electricity flows through a wire. Well done!

Nice job explaining this. I can read this until I'm blue in the face, but as a 41 year old with a Chicago public school education, your explanations are resonating quite well with me. I'm just wanting to learn some basics as a hobby and now as a home owner I think it's good to know how all this works. Thanks for making these.

CodeNMore is like the teacher we wish for he literally said don’t worry I’ll recap it at the end

Thank you for this! I'm a hobbyist and have always loved working on projects building PCs, drones, taking a part my refrigerator LOL. I've gone through life working with electronics and guessing my way though voltage, current, power and doing fairly good. This course really helped me bridge the huge knowledge gap that I've had, and really "married" the information I had with very solid concepts from your series. You are very good at what you do, you are the type of person that was born to do this! keep up the good work!

Hi Tony. Man, I'm really enjoying these electronics tutorials and how you explain things for a not so electronically inclined person like me.

This is simply awesome! I just developed an interest in electronics, bought a "beginner's book" (and components kit) and I was left with more questions than answers. The writer provided very convoluted explanations, assumed knowledge I didn't have and I was left confused and a wee bit frustrated. Thank goodness for your series. Your concepts and teaching style makes a seemingly complex topic easy to understand for us newbies. Bite-sized, logically sequential and not at all presumptuous. Great job! Subscribed.

4 years of undergrad later.... and this single youtube video taught me more than I got out of my senior year. Bless u CodeNMore. Bless you.

I love how you use water to give a mental picture of the differences between Voltage, Current, and Resistance. My kids love it. I actually told my kids to think of Resistance like a faucet's shutoff valve. We don't change the size of the pipe (wire) but by adding a shutoff valve we can adjust the flow of water through the pipe.

Hey man, I am barely in your fourth tutorial about beginner electronics and so far I think you are awesome at teaching and just wanted to thank you, I want to learn about the topic and I think your tutorials are gonna really help me, once again thanks

excellent explanation no one i know has explained what a resistance is like you ! wow i am going to learn a lot from you pal please keep this good work up

Great series, hope you find the will to continue it.

Thanks, dude that helped a lot in understanding current, voltage, and resistance. Explained like a pro. You explain a lot better than my college teachers. I'll definitely recommend your channel to my mates. Thanks a lot again.

We are four vids in in 4 days a new record for me. Thank you brillaint stuff! Can't wait to play with it but holding off as per your good advice at the beginning.

EXCELLENT TUTORIAL! You explained something so well and so simply that I understood it in 8 minutes. This is something that my physics teachers couldn't explain for hours.

I really enjoyed this video (and the series so far). Are simple enough to get easily understandable and in the same time they contain enough information to feel that you learned the things you were looking for. I wish school or even uni was that good when I was doing subjects about electricity/physics. I remember that were my most hated subjects (purely because of the overall presentation in books and how teacher were approaching it). But now I am so hyped to learn more.

this series IS EXACTLY what I was looking for!!! please keep making this series. I love it.

six years later. I am watching this from Saudi Arabia and I'm so thankful for your lessons. They are so easy to understand. God bless you man.

thank you for this series, it's amazing, it's so easy to understand. Other tutorials talk like we know something but oyu take us from the ground and explain what the ground is, it's perfect!

Really appreciate these vids and your great way of explaining things simply, im doing another electronics course thats supposed to be for beginners but they complicate it way too much for how early into the course it is ,im learning way more and it's sticks in my head from your videos so thank you so much 😊

Fantastic! Here’s another analogy and a quick summary: 1. There are TWO Tanks, T1 and T2. 2. They each contain the same VOLUME (quantity) of toy cars. VOLUME = VOLTAGE. 3a. T1 has a FAT pipe connected. FAT = LOW RESISTANCE (like an 8-lane highway). 3b. T2 has THIN pipe connected. THIN = HIGH RESISTANCE (like a 1-lane highway). 4a. T1’s FAT pipe allows MORE cars pass to along the highway per second or per mile 4b. T2’s THIN pipe allows FEWER cars to pass along the highway per second or per mile 5. The RATE at which each tank’s total cars pass along their respective highway is the (NUMBERS OF CARS ON ALL LANES OF THEIR HIGHWAY) / minute or mile 6. RATE = CURRENT 7a. T1’s RATE is HIGH 7b. T2’s RATE is LOW So ... Same VOLUME (quantity) of cars + FAT highway -> High flow RATE Same VOLUME (quantity) of cars + THIN highway -> Low flow RATE The End. You’re welcome.

Wish I had seen this video 7 years ago, you sir excelled at explaining what resistance is!!!

I’ve taken like 3 electronics courses and I finally think I understand the difference between voltage and current. I knew the definition, but I never fully grasped what it meant. Great video!

BRO U DESERVE MORE SUBS, PLEASE CONTINUE WHAT U ARE DOING. I'm a first year student of electronics engineering and I'm nervous because i don't have much experience with this kind of field. Hope you will continue this journey! More blessings!

I've seen OHMS labels all my life, the word resistance too in electronics. Never actually knew what they meant. This is a very nice analogy. Not difficult to understand at all. Thank you.

At school: wtf is this, has no point, makes no sense, insane... This tutorial: lol this stuff is simple as hell :0

Really liking these tutorials. this is basically exactly what I have been looking for. I look forward to watching more! Thanks.

Thanks Bro. My ear is too slow to catch your name as you sprint it too fast for me to legally hear.. But I am thankful for your very clear and precise tutorials. I am following them strictly. I want to be doing meaningful projects later on for some remote areas in my country to help them with water and electricity. More Power to you!!

Nice job! I think, it’s crazy in today’s world to not be curious about how things work and I don’t want to be left behind

I like this teaching pace very much! Fits my brain perfectly!

WOW! This the best Explanation I have ever seen on youtube! Very clear and to the point. Thank you bruh

This is first explanation of difference between Volts and Amps that made sense to me. Thank you!

Incredibly wonderful brief, direct and clear

That's so clear! At school when I still had physics I was like "what in the world is resistance??" and now that I watched your video I totally got this concept, thanks a lot!

Just came back to this video and did some researching on some key words that I heard and was able to get a better understanding now thank you codenmore

thank you for these, i'm from slovenia and i find your tutorial more simple in english then all of the tutorials for "Dumbs" in Slovenian. Amazing.

This is a great series. It’s totally beginber-friendly. Great job!👍🏼 BTW, the horseshoe symbol for ohms is the Greek letter Omega.

Thank you so much, this is awesome, i have been looking for a tutorial like this forever. Great job.

Just want to say thank you for this series. It's easy to watch and understand for a beginner. :)

Ty sir for ur explanation with clear examples. At first during my first class in clg I couldn't not understand what is voltage and resistance practically. Now I can understand how electricity works.

BRO. this is phenomenal. i never thought of voltage being described that way. you should be a teacher. that was extremely helpful. when i took physics in high school and my teacher taught me this, if he explained it in this manner.... idk it would have changed everything about my understanding electrical circuits

Fantastic!As a kid i was always interested in electronics, but after a while my interest faided away as i had more and more other responsibilities. And the subject came back at school, but i was not pleased by the depth of the information given. I wanted to pick up something i am actually passionaite about. And i am happy that i came across this serie of lessons.Subscribed.

Dude wish my teacher was this clear and concise in class. Thanks for the playlist!

Instead of "size of pipe", I would suggest using an analogy of valves OR of materials filling the pipe (sponge, sand, etc) to describe "resistance". Either analogy would slow the flow rate even as the pipe remains the same size. It might be less confusing since, as you said, we don't actually change the size of the wire in order to change the current.

This guy is a legend. Everything is easily understood. Subscribed

Thank you so much! I recently got interested in electronics and you explain it very simply, thanks alot 😊

Thank you so much for this great series! This stuff is amazing!

greart really i love the way you explane, thank you

Thank you so much for demystifying electronics for me,very much appreciated!

3 months of physics in 8 minutes with no details lost . Well done

First of all bro, thanks for the great content. I've been searching for introductory electronics videos and yours are just as good as all classes should be. I think that the current has been a little bit bad defined. In physics when we talk about a flux it's basically an infinitesimal area times a number of entities. In the case of the current it would be the side area (sorry, I don't know the right term for this in english) of the wire times the number of eletrons. So, if you get a larger wire (one with a bigger radius), you'll be able to transport more electrons an enhance the current. Furthermore, the definition of resistence is r = (lenght of wire)/(side area of wire). Therefore, again, the larger the wire, less resistence you'll have and because of that, more current

I am lucky enough to see such a wonderful tutorial ... thanks!!!

These are very easy to follow tutorials. Thank you.

What the...!!! This is definitely the best video, explaining this stuff, i ever saw. I also hope you will continue this series. SUBSCRIBED SIR!

You made me love electronics. You are the best.

You are a genius. You know how to teach and to pass knowledge.

God bless this guy, thank you for teaching us because you're doing such a great job of explaining things really.

I’ve never understood the current properties as you did. Thanks 🙏

I like the way on how you educate every viewers in a fundamental theory using a practical illustration to fully can recollect a scenario of lessons in the beholders eyes. For this bec i love studyings eventhough i have a sort of knowledge about electronics well, education is a free unended process of learnings and i guess i would compare my self to such an (AC) alternating current. Wherein, when i know something new i proceed then another learning of process then alternate and then resumes my continuity current of learnings and so on... thats how i use to compare myself... and in such a way to become a (DC) lol, its a fix voltage of lsssons that i've got from the AC. Herein your series topic about flow + resistance is another good series lessons i will enjoy having with to be learn of and i want to have it...I'll give my sub for you as a sign of mmm making your effort with a fruits of gettings. Thanks

Such a great analogy, well done.

Excellent explanation..i love ur all videos...

Your teaching is so interesting thanks.

Super work!! I am loving it :)

Top ! Keep up the good work! When can we expect the other tutorials? Greetings from Belgium...

This is the best series ever😍😍😍😍😍

u r the one in best teachers list,thanks sir

Great! Simple and clear! Good job buddy!

Your explanation is awesome! Thank you!

This 8 and a half minute video taught me more than 1 term of an electricity and electronics class,, 🤦 Great video lol

I finally understand the difference between voltage and current now, thanks

Well done! Very well explained. Thank you

Now this is the easiest way to understand electronics. U rocks dude !!!

I finally get it!!! These are so great.

This was great! So easy to understand. Thanks!!

I first learned about resistance when my first husband's extension cords all over his floor melted and made stinky smoke in the trailer. I learned that if I didn't want too hot a wire, to get bigger wires. That was my take home lesson. Or my prevent the home from burning down lesson. And yes, on solar, we (second hubby, still knows less than me about it) still use a lot of extension cords and it's hard to find 12 AWG or larger extension cords.

Amazing. Thanks for your work!

you are the science teacher we all needed

Beautiful explaining

love what youre doing man! thanks!

Thanks for these vids ! Yup , a larger wire means more electrons and current but the water example is a false one . The same volume of water per time unit passes in a smaller tube under the same pressure , which requires the water to move with a higher velocity ( According to the continuity equation ).

you are doing a great job. Keep it up mate

I loved this series 😍

Thank you, thank you so much 🌱 Keep growing :)

This series is great!

Okay. So far so good! This is fun! Your voice kinda reminds me of the guy from Game Theory a little. :)

Very easy to understand. THANK YOU

I refreshed this like 8 times thinking only the audio was loading until I checked further into the video and noticed that it's just black until 0:38

These tutorials are amazing

Thanks so much for these videos!

Excellent vids pal.

Awesome teaching technique sir 💐🙏👍

I'm trying to have a good way to explain this subject to people. I think, the way you did is a good way to start! But, than on, you have to be more specific and add the in depth of every subject you all ready explained until this point. In any case that is great!

Thanks for this, well expalined

Thank you! This helps me understand!!

Hi there. we are waiting for the next clip. Thnx

God bless you for sharing your knowledge
