Question

which term describes the amount of energy that is used in a circuit each second?
a. current
b. resistance
c. voltage
d. power

Explanation:

Power is defined as the rate at which energy is transferred or used. The formula for power \(P=\frac{W}{t}\), where \(W\) is energy (in joules) and \(t\) is time (in seconds). So, power gives the amount of energy used per second.
Current (\(I\)) is the rate of flow of electric charge (\(I = \frac{Q}{t}\), \(Q\) is charge). Resistance (\(R\)) is a measure of how much a component opposes the flow of electric current. Voltage (\(V\)) is the electric potential difference between two points.

Answer:

D. Power
