If a full wave rectifier circuit is operating from 50 Hz mains, the fundamental

If a full wave rectifier circuit is operating from 50 Hz mains, the fundamental frequency in the ripple will be

(a) 50 Hz
(b) 70.7 Hz
(c) 100 Hz
(d) 25 Hz

100 Hz

In a full wave rectifier, Fundamental frequency in ripple = 2 × input frequency

Fundamental frequency = 2 × 50

Fundamental frequency = 100 Hz.
