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
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → \( 60\,\mathrm{Hz} \)
A half wave rectifier passes only one half of every input cycle and blocks the other half. So each input cycle gives one output pulse, and the output repeats exactly as often as the input.
\( \displaystyle f_{\mathrm{out}} = f_{\mathrm{in}} = 60\,\mathrm{Hz} \)
