Question

The peak voltage of an AC source is 126 V.What is the rms voltage?
A) 63 V
B) 178 V
C) 89 V
D) 126 V
E) ​95 V

Quizplus · Accepted Answer

The rms voltage of an AC source is given by the formula Vrms = Vp/√2, where Vp is the peak voltage. Substituting Vp = 126 V, we get Vrms = 126/√2 = 89 V (approx). Therefore, the correct choice is C.

The Peak Voltage of an AC Source Is 126 V
