Question

The current through a 12W resistor in an electric circuit is 1.5A. Calculate the potential differences across the resistor

Answer 1

Answer:

Potential difference = 8 Volts

Explanation:

Given the following data;

Power = 12 Watts

Current = 1.5 A

To find the potential difference;

Power = current * voltage

12 = 1.5 * voltage

Voltage = 12/1.5

Voltage = 8 Volts

Therefore, the potential difference which is the same as voltage is 8 Volts.
