Question

Ripple frequency at the output of bridge rectifier when the transformer primary is connected to A.C. mains supply is (A) 100 Hz (B) 50 Hz (C) 25 Hz (D) 75 Hz ​

Answer 1

=> a ) 100 Hz

Explanation :

[ Basically in India the input frequency used is 50 Hz ]

In Full wave rectification,

In output wave, the -ve cycles are also converted into +ve one.

[ refer the attachment ] so as per the frequency, input completes one wave in given time where as output completes two waves i.e 50 × 2 = 100 Hz

Thus, The ans is 100 Hz !
