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

Answer: (B)

$50Hz$

In half wave rectifier, negative half of an ac.cycle is removed from the sinusoidal pulse, but the time lag between two positive pulses is same, hence frequency remains same as the input (mains) frequency i.e., $50Hz$.
