Based on the understanding operations of rectifies answer the questions Diodes can be used for rectifying on ac voltage (restricting the ac voltage to one direction) with the help of a capacitor or a suitable filter, a dc voltage ca be obtained.

In half wave rectification, if the input frequency is 60 Hz, the output frequency is

60 Hz

The correct answer is option (3) : 60 Hz

In half wave rectifier $f_{out}=f_{in}$

$⇒f_{out}= 60\, Hz$
