Question

The rms value is _________ times he maximum value

(a) 1.414

(b) 0.5

(c) 2

(d) 0.707

I had been asked this question in examination.

I'm obligated to ask this question of Phasor Diagrams Drawn with RMS Values Instead of Maximum Values topic in chapter Alternating Voltage and Current of Basic Electrical Engineering

Answer 1

The correct option is (d) 0.707

The best I can explain: We know that the rms value is 1/√2 times the maximum value, hence the rms value is 0.707 times the maximum value.
