Question

Power is defined as the energy expended per unit of time. When translated to electrical terms, power is equal to

A. current divided by time.
B. current multiplied by resistance.
C. voltage divided by time.
D. current multiplied by voltage.

Answer 1

In electrical terms, power is the product of current and voltage, represented by the formula P = IV, measured in watts.

Step-by-step explanation:

Power in electrical terms is the rate at which electrical energy is converted into another form of energy. The formula for electrical power is P = IV, where P stands for power in watts, I denotes current in amperes (amps), and V represents voltage in volts. Therefore, the correct answer to the question is D. current multiplied by voltage. For instance, a household circuit breaker that allows a maximum current of 15 Amps at a voltage of 120 V would equate to a maximum power of 1,800 W (1.8 kW).
