Question

A capacitor of 220 V, 50 Hz is needed for AC supply. The peak voltage rating of the capacitor is ____________

(a) 220 V

(b) 460 V

(c) 440 V

(d) 230 V

I got this question in semester exam.

This intriguing question comes from Advanced Problems on Two Port Network topic in portion Two-Port Networks of Network Theory

Answer 1

The correct option is (c) 440 V

Easy explanation: We know that,

Peak voltage rating = 2 (rms voltage rating)

Given that the RMS voltage rating = 220 V

So, the Peak Voltage Rating = 2 X 220 V

= 440 V.
