Question

Quizplus · Accepted Answer

The rms (root mean square) value of an AC current is defined as that steady current which, when passed through a given resistor for a given time, produces the same amount of heat as the actual AC current does in the same resistor over the same time. This is a measure of the effective value of a varying current.
