Question
In the half wave rectifer circuit operating from 50Hz mains frequency, the fundamental frequency in the ripple would be
Options
A.25Hz
B.50Hz
C.70.7Hz
D.100Hz
Solution
In half wave rectifier, negative half of an a.c. cycle is removed from the sinusoidal pulses pluse, but the time lag between two positive pluses is same, hence frequency remains same as the input (mains) Frequency i.e. 50Hz
