Ohm's Law, The Basics 

Richard, you have a knack for teaching. With your vast knowledge and experience in electronics you are a gift to us here on RU-vid. Thanks for sharing your time and knowledge with us! I hope you never grow tired of making these videos! We love em!

Thanks man.. I have bad anxiety and I was stressed over a test I have on this tomorrow. I was having a bit of a melt down but this really helped me figure it out. I really appreciate you taking your time to make this video

My job in the USAF, 1966-70, was aircraft instrument indicating systems repair. It was a great job and I learned a lot and work on lots lots of aircraft, mostly C130's, F4's, B52's. I did a few video on it.

This cleared a lot of misconceptions up for me. I thank you for going over both a series and a parallel circuit. Cheers^^

very enthusiastic

Sr. I wish I had come across this explanation over Ohm's law a year ago when I had to take AC/DC class in college. Very well explained, thanks for sharing!

You sir are an absolute GENIUS! Thanks so much for simplifying this. You have earned another subscription.

The Effort You put into these Videos is Nothing Short of Outstanding!!! It Makes For a Great Refresher For A Old Timer such as Myself!!! 441 Likes are Backing Me on this one..Many Thanks Once Again!!!

this guy explains it better then my electronics teacher. thanks

The right teacher makes everything easier to learn...53 yrs old and it finally seems simple

Those are some very cool aircraft, I'm sure they keep you busy. You are getting some very fine training and learning some very valuable skills. After all these years I think of my time in the military most every day. And all it takes is a plane to fly over. Learn all you can, it will be very valuable to you.

The cadence and prosidy of your voice is perfect. Nicely done sir.

@sithwarrior26 E=I*R=1.02*100=102, I rounded up the 17.89 to 18. Using only two digit calculations introduces a small error, thats why I rounded up to remove this error. And I used two digit calculations because the answers would fix on the video screen.

Two or more resistors in a parallel group, the total resistance of the parallel group will always be less than the smallest resistor that is in the parallel group.

Hey Rick, AAFR, Thankyou for all the great electronics educational video tutorials, I appreciate the time and effort you put in making them & look forward to more in '16. Have a Happy New Year & All the Best in 2016. Take care, Cass.

Thanks making is so simple. Simple is best and my dad is getting me an interview with the vp of an electrician company for a electricians apprentice. I am going to see how it goes and if needed to to wyotech for the electricians course if needed. I need al the youtube I can get. Thanks for helping my horrible memory understand this much better.

Thanks sithwarrior26 Technical material sometimes takes awhile to understand, it does for me. Because of course and then job requirements, I took some form of basic electronics seven times, and learned something new each time.

your videos are seriously saving my life in my auto electrical class. so thank you very much for helping. i thought id never get it.

That is exactly what I do in the Navy. I have worked on CH-53 Sea Stallions, MV-22 Ospreys and AV-8B Harriers.

I'm an AT (Aviation Electronics Technician) in the Navy and the Ohm's Law is our TOP foundation. I always had difficulty with Parallel circuits but now I understand it completely. Question is it necessary to round up the voltage in an parallel circuit to figure the voltage drop to each resistor? Meaning would it be expected to round up to simplify the math? Thanks again! HOOYAH!

I'm in grade 11, and i have a test tomorrow and doing these calculations were what was worrying me the most. But not anymore thanks to your excellent explanation! You made it very easy to understand, so thank you very much! :)

You are like the Bob Ross of eletronics. I feel at peace lol.

How can such a simple formula, tell so much about electronics? Georg Ohm and algebra: both have made great contributions to our everyday life! RL

I recently subscribed to your channel. Many of those who have an interest in electrical and electronics will find your videos helpful. When I was proficient at reading I started teaching myself about electricity back around 1964 when I was 10 years old and going to the library to get books. That turned out to be a blessing as I started a profitable hobby fixing things electrical and electronic, like CB and amateur radios, and other electronic devices. I'm also self-taught in many other things like plumbing, carpentry, auto and motorcycle repair. Unfortunately, technology has outpaced me and I'm more into fixing older and simpler things. For the record, I'm not into the occult, I don't cast spells, and I'm not a real 'Wizard', it was just a nickname I was given as I can fix many things. de KC8FLU

Thanks to this video I can now begin my journey... to explain the relations of each circuits

thanks so much im currently studying for my ham radio licence and have been really struggling with ohms law

This has been super helpful. I have been taking Electrician as my electives and it definitely paid off watching this video several times. Although I am confused at the moment when encountering "E=I2R" on the tests as one of the answers for definition.

Thank you for taking the time to show people this very informative and very well done

Same reason that Pluto is now not a planet, somebody wanted to change it. It still is what it is. And Pluto could not care less.

Thanks, the vid helped me a lot! I did wind up watching a few more times, making notes as I went. I figured out where my mistakes were. I was misunderstanding what was being measured in the parallel side of the circuit.

Great for repetition, its been nearly 3 years since I had this in school now. We (here in Norway) learn that the formula is U=I*R, or to simplify it for those who didn't understand it: V=A*R. I remember that this stuff was hard to learn, as we had to learn both the american and european symbols in electronics. Very easy to mix it together sometimes. -Frank

Thank you, Better than in the class room

This is the best video I've seen yet. Thank you!

Thanks I'm working on an Ohm's Law Demo video. I should upload it sometime this week.

Thanks CameramanLink I have put this in my RU-vid List folder.

Thanks for your teaching methods with very simple method. I am your favorites youtue channels subcriber from India-Chennai.

Hi there this video was really helpfull although im 38 and want to learn for my personal enjoyment this video was so easy to understand and follow. I have now subscribed to your channel. Thank you

excelent, thanks, I can't believe I had to drop an electronics class long ago for not knowing this, and my teacher got upset if I asked him this basic staff......thank u again.

Awesome video and concept! Keep up good work mat. Regards,

Thank you for this superb demonstration of Ohm's Law.

another great video! I wish i had your videos when i was learning these principles

did my first paper in college on Georg Ohm. Fascinating man

You are a very good teacher! Please do more videos like this!

THANKS!!!! I read the book 3 times, did not get it until I watch your video.

Very enticing to learn :) awesome to find out the unknown value.

Excellently made visuals. Thank you.

A great help for my demonstration! Thank you !

Thanks and I've been there many times

amazing i am blessed , thanx and i also loved the man's voice

@Nadiah2111 Sure you can use it, I have no restrictions on my videos. Several instructors are using my videos in class.

@sithwarrior26 total I is = 1.02A then use E=I*R that is E=1.02*100=102v if the total voltage is 120v remaining is 18v now you can divide 18v with other resistors to find the voltage across them

I also didn't really understand that part, so I asked my physics teacher and he told me it is just not possible. Or you have the current and the resistance or you have the current and the potential difference (voltage) or you have the resistance and the potential difference. Hope I helped... Good luck!!

Thanks rlewis1946 The basics are extremely important. This is what everything is built on.

That just cleared up a lot for me. Thank you

@CrazyApe360 What types of circuits are you looking for? I have gone through several circuits in detail. Also download my ebook and the Navy Training Courses. The links are on the My Channel.

This is so helpful!! Could you do a similar video for Q=CV?

Beautifully explained. Thank you!

I just wonder why the 32 pricks were thumbs down? this is the best video ever in the u tube. well done mate.

I got confused on the parallel voltage part. did he round the 17.89 volts up to 18?

Thank you for this video, it's very clear and simple now.

This was very useful since I didn’t understand this one bit and I gotta study for my exam

Thanks a lot. I saved your video. I couldn't understand this for nothing. Big help.

cheers man helping with my engineering BTEC

So where did the 1 come from? Thats what confuses me? How did you know to divide those resistors 55,35,95 from 1? Is that because there is only one power source?

it goes back to when current used to be called "impetus" which basicaly means the flow, or intensity of the current

+AllAmericanFiveRadio my Question, is how did you get the Decimal from the 3 Parallel resistors in Ohms? 1 over 55, 1 over 35 and 1 over 95 I think it was, how did you translate to point whatever number to get the resistance of that ohm?

Thank you soo much for producing this video. I was perplexed for days to the question of overall resistance. If i add a circuit onto an existing circuit, can i simply add more battery to make up the lost voltage? And if possible, add potentiometers to regulate power distribution?

Nice video... Pls post some more ckts, such as Bridge ckt etc. Very Helpful, Thanks

E for voltage? Blasphemy. E is reserved for energy or electric field.

Sir, great tutorial, but I have a question? Where did yo u get .018,.029 and .010?

that cleared my mind about parallel resistance and the inverse math without using a calculator

it doesn't matter, either symbol works

You saved me from a test, thank you

i can follow the formulas fine, but i don't understand how increasing the resistance in a parallel circuit decreases the resistance?

First of all, thank you. Second, do you have a playlist of basic Circuit Tutorials? I am just starting out and this video was very helpful. I tried going to your youtube site, but did not find any. Thanks again.

Very good explanation of Ohm´s Law! Cheers...

How did you get 17.54? I understand this: 1/.018 + 1/.029 + 1/.010 = 1/.057 but then what did you do?

okay so how do you get the volts from 100 to being 102 and from it being 17. 54 to being 17.89? what happened there that i'm not understanding?

What time in the video?

Thank you very very much for this video. It is very helpful Sir!

in the last equation how did you come up with 102Volts ? where did you get that number from

Thanks Rick, a very interesting video.

@MOJOATLBIGSHOTS 94 ohms and 5 volts max current would be 53.2ma

can i send u my circuit and can you work it out with working outs and etc?

is there a minus sign in the formula above?

@AllAmericanFiveRadio thanks for the vid.....what would happen if your circuit calls for 85 ohms but 94 ohms is as close of a resistor u can find for a 3.3v 20ma led with a 5v power source....i wanna keep my eye brows

How did you get 1 over .18+.29+.10 for resistance from 1over 55 1over 35 1over 95 my question

This is very helpful. Thank you 😊

Thanks fitzinabox That makes me very happen, keep learning.

WOW! thanks now i understand it clearly now ...Good job...

17.89 is actually too long to fit on the screen 17.89XXXXXXXXXXXXXXXX, also I'm only using two decimal points which introduces a small error. So I rounded up 17.89 to 18 to remove the error. If you use four or more decimal points the error will be much less.

This is helpfull video sir....thank you very much...

Algebra!!

Prefect explanation. Thank you.

100*1.02=102V

I knew i was doing something wrong, thank you! Great Video!

Thanks DeepRootsFilms

So splitting a bus doesn't split the voltage? Never new that...

@Nadiah2111 E=I X R This is the bassis, One Amp times One Ohm equals One Volt.

gracias por su tiempo y dedicasion me fue de mucha ayuda
