A VA rating is more relevant when judging the current delivery capacity for a given signal source.

Question

Quizplus · Accepted Answer

A VA rating is a measure of the apparent power of a signal source, which is the product of the voltage and current. It is more relevant than the real power rating when judging the current delivery capacity of a signal source because it takes into account the phase difference between the voltage and current.
