Question

In the half wave rectifier circuit operating with $50Hz$ mains frequency. The fundamental frequency in the ripple will be

• A. 100 Hz
• B. 20 Hz
• C. 50 Hz
• D. 25 Hz

Answer 1

Answer: (C)

In half wave rectifier, the output is obtained for half cycle only. Therefore, frequency of the ripple is same as that of the input i.e. $50Hz$.
