Volts

Question

I don't know under which math this belongs. It's electrical formulas. The problem says to use Watts Law but includes resistance in the Q. If Watts Law wheel is P=I×V but we have 4 categories on the hub.

Answer 3

Good Lord! That wheel is a monster. P = IV and V = IR. That and a little algebra is all you need! -Dan

Answer 4

Easy enough. I guess I was trying to make the Q adhere to the 3 category hub wheel.

Answer 5

Based on info given in Q, it would be this formula...

Answer 6

You have four quantities Volts (V) ; Amps (I) ; Power (P) and Resistance (R). If you know any two of these you can calculate the other two using the formulae in you coloured diagram. So if you want to know the Volts you look in the brown quarter and one of the three formulae will equal the volts using the two other quantities you are given. Can you see which one you need from your question?
