Oh ur sick man thx
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! ☺
Very clear explanations. Thank you for helping the concepts "click" so painlessly.
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.
for some reason I found this way easier to understand than others I've watched thanks!!
Thank's alot, just started an electrician course at home, this is my first day on it and already getting a great understanding
Did you become an electrician?
Thanks John! Great video and thanks for taking out the time to help others
Thanks JW. The best explanation I have ever heard and this has been something of a mental block for me.
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.

Thanks JW for your eloquent and simple explanations regarding all things electrical. I follow your videos with great interest, and I am learning much.
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
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.
this man explained 2 full 1.5-hour classes in just 20 minutes. Respect.
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
JW the best teacher! If JW taught at my school I would have put my Nintendo Game boy away.
Thank you,John!
This helped me a lot in my presentation!
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!
I clicked for the lesson
Stayed for the cool shirt
Left just a little bit smarter
Thank you kind sir
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
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.
gcse physics tomorrow. last exam. this was class, but your tshirt was even better.
O home formula Hindi
Pwede paturo
Sir you are a good teacher. Thank you
John, your a good teacher.
Thanks John for the videos they are very helpful !
Thank you very much for this memory refreshing video, John.
Cheers John. Great video I have a exam on Sunday morning.
great videos...REALLY USEFUL....Cheers John for all your videos.
Thanks for simplifying. Made it look so easy
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
Great refresher. Purse since my physics classes 30 years ago. :)
Nice teachings boss
This video is great video, thanks for taking the time out to shows us
Thanks for your wonderful ,brief and sharp eleboration . It's really help . Thank a lot.
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
Thank you so much for your video! It was so much easier now that you've explained it.
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:)
You would make a brilliant teacher!
your a absolute star mates.....helped me a lot!
Thank you very much. Everything was clear and they were easy to understand.
thanks for your time and effort to share the knowledge
Big thanks JW... top man👍
Best video on the subject, thank you.
Thank you for making this video. You're a very good teacher. Great to refresh ones knowledge.
Thanks John
Made it really easy to understand. Just subscribed
very clear explaination sir.they are very helpful thanks for this video.
Very good video. Thank You.
Explains everything in a lot of detail big help cheers
Joseph from Ethiopia
You are a perfect explainer,thank you very much.
Thanks for the information John.
Thanks for the lessons.... Enjoy your lectures very much.
Cheers
Excellent tutor, please post more of it.
Thanks John this was really helpful, cheers
very well explained you loove your subject I wish you had been my tech. teacher when I was training back in mid 50s thank you.
Thankyou very much, you have really helped me. Cheers from 🇭🇲👍🏻👌🏻👏👏👏
Brilliantly explained thank you very much
Really good video, well presented!
I rely thank your generous and valuable knowledge you share us .
iam so happy. stayblessed
Very Very Well Explained. Thank you so much for this video helped me clear a few things up 😀😀😀
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 .
awesome vid!! helped me with homework so much much thanks
Great video as always
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!
Excellent. Thank you.
good induction mate
I learned
The liked button works
Keep it up to many supporting you
brilliant video....
Excellent explanation.. Made it very clear and logical. Many thanks
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.
Wow Raj cv
Great lesson,easy to understand even for someone who a foreigner
Great professor.
Thanks Dude I passed my physics test 🤟🏼
this actually helped me with my homework.THANKS!!!!!
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
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.
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?
thanks, mr,John
So clearly explained............................ cheers
Great video!
Thanks, this helped.
excellent, learned this 35 years ago and never used it. Your explanation, Perfect!
TY
Good your formula is easy to understand .
Thanks a lot Sir 🙏 I find it really really helpful
I wish I had just a fraction of your knowledge.
You will if you keep watching👍
You will if you eat what your body is designed for and that is a plant based lifestyle.
@@obviouslytwo4u 🤣😂that’s so random but your probably right
Great vid. Any chance you could explain, series/parallel circuits? also fault finding and testing? Thanks
Beautifully explained!
that was great and informative- thanks John!
great job explaining,
i dof my cap to you sir...
Thank you.
Another great video!!
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 😅!
Johnny boy you are that dude from back to the future. MARTY lol you inspire your listeners
Thank you sir
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.
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?
Me too I don't agree on that point
Aap Jo be bola sur ka upar se nikal gaya
Lekin magic triangle and magic circle bahut useful hi
Thank you sir
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 CZcams from different countries , we're all speaking the same language, though sometimes not always understanding it .
Your video make me to easily understood relationship between VIRP thank you
This helped with my science revision
Great job👍🏽
