Oh ur sick man thx

[@abraxis6080]

Just wanted to say thank you for this fantastic simplified explanation John. You explain the symbology clearly and then show how to calculate each in a simplified manner. It took me a good hour searching to find this, but you have now shown me how I can simply find out the relevant values. Thank you for the time you put in and the clear explanation of the topic without over complicating it. I wish my maths teacher had been like this! ☺

[@ssjktjessica6]

Best explanation anywhere on line or classroom well done John, you should be a lecturer if you're not already one ,you've got that rare talent of explaining things in a way students can understand, well done sir

[@JKeyB]

Thank's alot, just started an electrician course at home, this is my first day on it and already getting a great understanding

[@rymichael7203]

Did you become an electrician?

[@mavezy]

JW the best teacher! If JW taught at my school I would have put my Nintendo Game boy away.

[@theSEGAtwistisover9k]

for some reason I found this way easier to understand than others I've watched thanks!!

[@SacredSalmonFish]

this man explained 2 full 1.5-hour classes in just 20 minutes. Respect.

[@markgoggin3677]

Thank you John, Your videos are excellent. I'm personally very grateful for you time & effort to make these. They truly are a great help. Thank you again Mark.

[@lasiodoraparahybana]

Thanks JW for your eloquent and simple explanations regarding all things electrical. I follow your videos with great interest, and I am learning much.

[@THECARKUS]

Thanks JW. The best explanation I have ever heard and this has been something of a mental block for me.

[@CasusUniversum]

Very clear explanations. Thank you for helping the concepts "click" so painlessly.

[@realviper1188]

I clicked for the lesson Stayed for the cool shirt Left just a little bit smarter Thank you kind sir

[@davidtreibs]

Sir, I have been pulling out my hair for the last hour or two trying to figure out something that ought to be pretty simple, but for some reason I couldn't figure out. I knew there were two formulas, and that they were connected, but couldn't quite put it together. Then I found your video, and your very helpful links on the times. Your explanation at 18:18 solved my dilemma. Thanks!

[@redmondkingsland2523]

Great videos JW. You explain the practical and in plain English way. You also sound like a BA pilot describing the journey ahead! quite reassuring. Red

[@pianoandviolin]

I love your videos. This is a great video for people starting out on electrical engineering. I wish I had you around when I was at college. Love the videos you make too of where you take things apart and explain how they work like trip switches etc... thanks for making them.

[@mikeyoneil6389]

Wish you was my teacher in school may be then I would have listened and had better exam results,love the presentation even someone as thick as me can now learn the basics thank you mr ward keep up the good work

Thanks John! Great video and thanks for taking out the time to help others

[@dinoLomedico]

Excellent video, let me tell you why . You keep lofty theory in bite size installments. You also write it all down, this slows it down and thus, gives our mind enough time to assimilate the information . Instead of intimidating us with knowledge through a clouded window, you keep the transfer of the data clear .

[@faridz7376]

Cheers John. Great video I have a exam on Sunday morning.

[@jrcortavista3562]

Thank you,John! This helped me a lot in my presentation!

[@ibrahimayoussouftoure7854]

Thanks for your time and trouble, you are actually a very good teacher. I wish you could do more videos on series/parallel on electric motors and alternator wiring? Thanks.

[@pauloneill5779]

John I love your video. I thank you for your time and trouble, you amuse and educate thousands. If you do requests I would love your take on technique of fault finding on circuits and practical testing maybe. Warmest regards

[@carloshortuvia5988]

Thank you very much for this memory refreshing video, John.

[@balzertordy2587]

Thanks for your wonderful ,brief and sharp eleboration . It's really help . Thank a lot.

[@markbeaudry2469]

John, your a good teacher.

[@jonpt2941]

Love your video, i seen this type off wall tons off times... I noticed you never put the triangle round, right away, that awsome because the more lines added the worst it is for my head to understand what I'm looking at... The less information fir my brain when explaining the better information gose in... Thus video where you used both triangle help me loads how they both work together! Any more like this be much appreciated

Another great video John.clear and concise.if you get time will you do a video on 'Clean Earths' i get confused with what should and shouldn't be on them.Thanks.You do great work

[@abihaile2391]

Joseph from Ethiopia You are a perfect explainer,thank you very much.

[@ryangray6543]

Thank you for this video, explained very well & helped me pass what i thought was a difficult electrical course. With these simple methods it was actually quite easy:)

[@sulemankihengere5440]

Thanks for simplifying. Made it look so easy

[@wowraj5305]

Thank You John for this video. This was explained very well. I hope you would make more videos on the basics of electricity for example when adding additional light circuits or plug sockets to your main connection and what you need to look out for.

[@Scotlanz]

Nice. Thank you. My main problem is finding out how long I can run a power amplifier from a wh battery so I get confused between amps and amps!

this actually helped me with my homework.THANKS!!!!!

[@johnhenry4113]

John, I do like your videos and I know you picked 480v to make the maths easier. However, would have been better if you selected actual voltage on 3 phase circuits - 400 volts.

[@cygnus108]

Excellent explanation.. Made it very clear and logical. Many thanks

Excellent tutor, please post more of it.

[@mostafaabdelrauof3185]

When I try to relate these laws with the transformer which rise the voltage and and decrease the amp and vice versa .. my brain can not accommodate it 😅!

Thanks for the great vid. Just a question-- In fixing any electrcial gadget, if the resistance is low than what's required, how do we go about it?

[@gazdkw82]

Great video as always

[@abrahimyehia9546]

Very Very Well Explained. Thank you so much for this video helped me clear a few things up 😀😀😀

[@busman2000]

It has been said many times, but I have to echo the sentiments of others' You are so much easier to follow or understand than my Tutor and he had an adult teaching certificate. I unlike your main audience come from New Zealand, apart from a few different industry terms I think we're all singing from the same hymn sheet. As Scottie said " Captain Ye can nay change the laws of physics" and I find this as I view inputs on KZbin from different countries , we're all speaking the same language, though sometimes not always understanding it .

[@maslak]

that was great and informative- thanks John!

[@rayknn]

To be really honest with you. You should see this as feedback. I don't think this explanation video is very aducative. It pretty much explains how to do math. We should be given real world examples. How volts and amps behave in a circuit, a battery etc. For people just wondering how you can do algebra this video is for you.

[@TheJask101]

Brilliantly explained thank you very much

[@1234a-x4o]

This helped with my science revision

[@kurtisgee3414]

Hi John, Thank you for your video. This is obviously for AC correct? Does this apply to DC? Example if you connect 6 x 6 volt 4 amp batteries together in a way that makes 36 volts at 4 amps. What is the resistance and the watts supplied? Regards Kurtis

[@ianharrison6597]

Very good video. Thank You.

[@friedmule5403]

Great lesson, easy to understand! :-) What about a Vandagraph that can make thousands of volts but nearly no current, how do that fit in if voltage and current raises together?

[@andrewkaindu7281]

Me too I don't agree on that point

[@user-marco-S]

With Ohm's law, you learned it with "V" (as in V = I x R ). I did learned it with "U" ( as in U = I x R ). According wikipedia, it differs from country to country which letter is used.

[@PerMejdal]

+Marco S Some even use E for volt.

[@user-marco-S]

+Per Mejdal Rasmussen I didn't know that, thank you. I did learn something which did use the E in some calculations, but it is almost more than 30 years ago (and not my job). Maybe it was something electronics-related. I don't remember, too long ago.

[@PerMejdal]

+Marco S I did some research and found U="unterschied" (difference in German) and E="Electromotive force".

[@user-marco-S]

+Per Mejdal Rasmussen Thank you.

[@xtcshri222]

Great video!

[@irepairlabs]

brilliant video....

[@sugreevsran766]

This is late at night, and it's probably a dumb question but suppose I know the Power and Resistance, how do I go about finding the amps or volts?

[@jwflame]

Amps is the square root of power/resistance, voltage is the square root of power x resistance. If you search for 'ohms law wheel' you will find a circular diagram which contains all of the combinations of power, voltage, resistance and current.

[@sugreevsran766]

Thanks!

Doesn’t resistance increase if the temperature increase

[@jwflame]

Yes, although for most purposes the increase is not significant.

JOHN WARD what is the formula to get "how much current in amps" can a 4700uf cap can hold from B+450vdc from a linear power supply?
