Question

In the half wave rectifier circuit operating from $50Hz$ mains frequency, the fundamental frequency in the ripple would be

• A. $25Hz$
• B. $50Hz$
• C. $70.7Hz$
• D. $100Hz$

Answer 1

The correct option is B $50Hz$

In half wave rectifier, we get the output only in one half cycle of input a.c. therefore, the frequency of the ripple of the output is same as that of input a.c. i.e. $50Hz$
