Alternating Current and Voltage - Technical MCQs

Q1:

What is the average voltage when a rectangular wave's base line voltage is 20 V, its peak-to-peak voltage is 50 V, and its duty cycle is 20%?

A 26 V

B 30 V

C 40 V

D 45 V

ANS:B - 30 V

Vavg = (2 * Vm)/π
So, put Vm = peak to peak = 50,
And the ans will be = 31aprox.
