Q. Frequency of given AC signal is 50 Hz. When it is connected to a half-wave rectifier, the number of output pulses given by rectifier within 1 s is
A) 50
B) 100
C) 25
D) 150
Explanation
(a) In half-wave rectification, there is only one output pulse for each complete cycle of the input AC voltage. Therefore output frequency is same as that of AC supply frequency, ie,
$f_{out} = f_{in}$
So, pulse obtained in 1 s by half-wave rectifier will be 50.
