In the half wave rectifier circuit operating from 50 Hz mains frequency, the fundamental frequency in the ripple would be
Options
(a) 25 Hz
(b) 50 Hz
(c) 70.7 Hz
(d) 100 Hz
Correct Answer:
50 Hz
Explanation:
In full wave a.c. or half rectified, the time interval between two peaks are the same. But in half wave rectification, the negative wave part is cut off. But as for frequency or the period, they will be the same as seen from the figures. Therefore, this also will be 50 cycles/second.
