Question

what is the current in a 5 ohms resistor due to potential difference of 20 V.

Answer 1

use Ohm's law: \[V=IR\]rearrange to solve for current, and you will get 4 Amperes

Answer 2

i get it already, but im confuse about the part that it say, due to potential difference , how about that?

Answer 3

Potential difference is same thing as voltage. Physicists say potential difference, engineers say voltage (joke :-).

Answer 4

really? okay.. thanks.
