The potential difference across a resistor is 12 V. When a current of 5 A is flowing through this resistor, what is the power used by the resistor?
A) 2.4 W
B)60 W
C)300 W
D)1500 W

Question

Quizplus · Accepted Answer

The power used by the resistor can be calculated using the formula P = IV, where P is power in watts, I is current in amperes, and V is potential difference in volts. Substituting the given values, P = 5 A * 12 V = 60 W.
