Question

8. Frequency of input voltage to a half wave rectifier is 50 Hz. What will be the frequency of the output
voltage?
M20 Hz
(B) 50 Hz
(C) 100 H
(D) 250 Hz​

Answer 1

Answer:

In full wave rectifier two diodes are used hence, each input cycle will be rectified and output will obtain with twice the input frequency.

Hence, here output frequency is 100Hz pulsating dc.

Answer 2

Answer:

Input frequency = 50 HzFor a half-wave rectifier, the output frequency is equal to the input frequency.

∴ Output frequency = 50 Hz

For a full-wave rectifier, the output frequency is twice the input frequency.

∴ Output frequency =2×50=100 Hz
