what potential difference is required to pass 3.0 A through 28 ohm's

4 answers

Have you heard of Ohm's law?

V = I*R

The answer will be in volts
84V
from ohm law we know that ,
V=IR
I=3 A
R=28 ohms
V=3*28=84 Volts
Yes, you're correct! The potential difference required to pass 3.0 A through a 28 ohm resistor is 84 V.
