Hi
I currently studying 2330 Lv3 to become an electrician. I've never understood where these formulas come from. I've always managed to get by just taking them for granted. Never really did use them at Lv2. With a 50% failure rate nationwide it's crucial for me to be able to remember these formulas.
I understand what's squared and square root means, I don't understand how the formula becomes to be V(squared) /p for example
I'm assuming they're transposed some how from a formula. I would appreciated it if you could shed some light on this. Driving me nuts.

Code:
R x I (squared)
V(squared) / R
square root(P x R)
p/ I (squared)
V(squared)/pI understand what's squared and square root means, I don't understand how the formula becomes to be V(squared) /p for example
