Alternating Current and Voltage - Technical MCQs

Q1:

An rms voltage of 5 V is equivalent to ___.

A 14.14 V peak-to-peak

B a peak value of 5 V

C 10 V peak-to-peak

D an average value of 7.07 V

ANS:A - 14.14 V peak-to-peak

Irms = 0.707*Peak value.

Peak value = 5/0.707.
= 7.07.

Therefore peak to peak value=2*peak value = 14.14.
