Q1:

A class A chopper has an input voltage of 200 V. Ton = 1.5 ms and Toff = 4.5 ms. The duty cycle, average output voltage and ripple factor respectively are

A 0.5, 100 V and 1

B
0.25, 50 V and 3

C 0.25, 50 V and 1

D
0.5, 100 V and 3

ANS:B -

0.25, 50 V and 3

The Average voltage is 50, and rms voltage is 100, ripple factor is rms/average. How come it is sqrt of 3?

Please tell me if I miss something.
