Final answer:
The potential difference required to drive a current of 3A through a resistance of 5 ohms is 15V.
Step-by-step explanation:
In order to calculate the potential difference required to drive a current of 3A through a resistance of 5 ohms, we can use Ohm's Law.
Ohm's Law states that the potential difference (V) is equal to the current (I) multiplied by the resistance (R).
So, in this case, the potential difference required would be:
V = I * R = 3A * 5 ohms = 15V
