Question

You have a simple circuit that includes a resistance device of 50 ohms, and the current flowing through it is 2.0 amps. Solve for the potential difference of the batteries.

Answer 1

Using Ohm's Law, we have that

V = I * R

Where V is the voltage of the battery (potential difference)

I is the current flowing through the resistance R

V = 2 A * 50 ohms = 100 V
