Question

What’s the potential difference across a 5.0 resistor that carries a current of 5.0A

Answer 1

V=25.0V

Explanation:

Ohm's Law formula states that

V=IR,where

V=potential difference

I= current

R=Resistance.

From the question, I=5.0A and R= 5.0Ω

By substitution,

`\implies V = 5.0 * 5.0`

`\implies V =25.0 V`

Hence the potential difference is 25.0V
