In half-wave rectification, what is the output frequency if the input frequency is 50 Hz. What is the output frequency of a full-wave rectifier for the same input frequency.

Answer

A, B

Explanation

A half - wave rectifier conducts once during a cycle. Therefore frequency of AC
output is also the frequency of AC input i.e 50 Hz. A full - wave rectifier rectifies both the half
cycles of the AC output i.e it conducts twice during a cycle .
So , Frequency of AC output ` = 2 xx` frequency of AC input
` = 2 xx 50 = 100Hz ` .
