The rms current is equal to the direct current that:
A) produces the same average voltage across a resistor as in an AC circuit.
B) provides the same average current in a resistor as in an AC circuit.
C) results in the same peak power in a resistor as in an AC circuit.
D) dissipates an equal amount of energy in a resistor at the same rate as in an AC circuit.

Question

Quizplus · Accepted Answer

The rms (root mean square) current is defined as the value of the direct current that dissipates the same amount of energy in a resistor as the AC current does over a complete cycle.

The Rms Current Is Equal to the Direct Current That
