    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! ☺

    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!

    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

    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 .

    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.

    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?

    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.

    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 TH-cam from different countries , we're all speaking the same language, though sometimes not always understanding it .
