you have the best math videos! thanks for the help!
Glad you have found it helpful Oliver, thanks for the comment
These videos are definitely going to help, sir. Many thanks again!
Andy thanks so much you are a brilliant tutor 😊
Please make more videos, i find you very easy to understand and you have helped me out loads thanks
Andy, thank you ever so much for creating and posting these videos about how to transpose equations! I've learned more from you in the past half an hour than I have in three weeks of reading my textbooks! You tuition was very clear and precise, and you made every step of the process so easy to understand! You've done a brilliant job! :-D
+Kate F Thanks for the lovely comment Kate and to all of you who have commented on the videos. I'm just so pleased that they are helping you.
Yea, you totally need to post more videos, specifically about electricity. I think the interweb would be on a winner if you did.
andy, thanks a million for these videos. i just started EEET level 2 from City Guilds and guess what they started with... i was lost on my first day, haven't been in a classroom in over 10 years. please do post more videos on these types of maths
Brilliant thanks
I thought X was actually L (Inductance)? And where XL is inductive reactance?
X is the symbol for Inductance and then you get XL for Inductive reactance and Xc for capacitive reactance. Hope that clears it up!
Hi, great video and very informative, I was really only watching to learn how to transpose - my maths is a bit....atrocious!! Just so happens that I am studying electricity mainly for fun..... Could you clarify a couple of questions please?
1. reactive power occurs when there is some measure of capacitance and or inductance that exists in the circuit, yes?
2. I understand that there always will be some Xc and some Xl but if there was such a thing as a fully resistive circuit would this then mean that V & I are completely in phase and thus Kva = Kvar?
I'm gonna check to see if you have any more videos, again the three I've watched so far have really helped. Thanks.

Hi Andrew. Your are correct in your assumption for question 1.
In a completely resistive circuit you are right - Current and Voltage are in phase so P = IxV - there is no reactive power so we are left with just power in Watts or Kilowatts.
For more complicated formula, is there a sequence to follow.
+chris hood. Hi Chris, yes there is a sequence for complicated formula. I have only concentrated on formula used in electrical science but try looking at this website for more complex transposition: mash.dept.shef.ac.uk/RearrangingFormulae.html
