In a full wave rectifier circuit operating from 50 Hz mains frequency, then the fundamental frequency in the ripple will be:

A) 50 Hz    

B)                        100Hz   

C)        70 Hz                    

D)        25 Hz

Correct Answer: B

Solution :

                When diode acts as full wave rectifier two diode valves are connected to obtain a continuous full wave output. Hence, fundamental frequency in the ripple is twice of operating frequency that is 100 Hz.
