The principle on which vector voltmeter is based is________?
Athat it works on the principle of complex variation
Bthat it measures the amplitude of a single at two points and at the same time measures their phase difference
Csame as digital meter
Dthat it measures the response of linear ramp voltage
Correct answer
B. that it measures the amplitude of a single at two points and at the same time measures their phase difference
Explanation
The correct answer is that it measures the amplitude of a single at two points and at the same time measures their phase difference.
