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

Options

A70.7 ~Hz
B100 ~Hz
C25 ~Hz
D59 ~Hz

Correct answer

B. 100 ~Hz

Step-by-step solution

For full wave rectifier, ripple frequency =2 input frequency array l =2 50 =100 ~Hz array Note A full wave rectifier consists of two junction diodes, so, its efficiency is twice that of half wave rectifier.
