Question

If in a full wave rectifier input frequency is 50Hz then output frequency is 

(A) 50Hz 

(B) 25Hz 

(C) 100Hz 

(D) 200Hz

Answer 1

Correct option is (C) 100Hz 

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

Correct option is: (C) 100Hz
