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.
Damn, i gotta spell everything out for you. Just dont forget to take notes when you watch thr video. You suck at shit talking. Go home then go to bed baby boy. Its passed your bed time.
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!
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!!!
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.
@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.
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! :)
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
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.
AllAmericanFiveRadio It doesn't. But I am taking online classes for electrician and on several occasions, the answers would appear as "E = I2 R". But I found out that it is a point where it is afterward rewritten as " E = I * I * R. " So the whole thing with I2 is just stating that you have to multiply that value by itself again before R.
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
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.
@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!!
@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.
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?
This is the formula for the total parallel resistance. 1/Rt = 1/R1 + 1/R2 + 1/R3 + 1/Rn This is from MOUSER www.allaboutcircuits.com/tools/parallel-resistance-calculator/
+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?
+Jimmy Warner It's Rt=1/(1/55+1/35+1/95), this is the formula for parallel resistors. And there is no limit. Rt=1/(1/R1+1/R2+1/R3+1/R4+1/R5+1/R6+1/R7+1/Rx....)
Ah ok i think i get it. Im just beginning on this. Trying to learn on my own. Gettinf into Crystal. Radios and Vape Mod building and want to lear s out yhe Mosfetd and resistors and the resettable fuses thats used in the circuitry.
+Jimmy Warner I'll by glad to try and help. The Vacuum Tube Shortwave Radio, free ebook www.richardmcwhorter.com/vacuumtuberadio/ Navy Electronic Course download page www.richardmcwhorter.com/NavyTraining/
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?
Kyle Robicheau That may be possible. But before I could really answer your question I would need to see the circuit that you want to modify and how you want to modify it. So another words I would need to know about the original circuit and you're purpose for changing the circuit.
+AllAmericanFiveRadio I don't know the resistance of either circuit, as this is a theorized project (I haven't started yet). I was planning to splice the leads to the original circuit, add potentiometers to positive wires, and close each circuit at the negative terminal at the battery.
I do know the potentiometers should remain at proportional differences to each other, but assuming different voltage drops, how could I make sure I don't overpower one of the circuits? I will be using linear potentiometers (that is about the extent of what I know).
Lamppis If I would've used a “V” instead of a “E”, then someone would've said George Ohm did not use a “V” he used “E”. The important thing is to understand the concept and to be able to use it.
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.
@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
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.
