Freuency of given AC signal is 50 Hz. When it connected to a half - wave rectifier, then what is the number of output pulses given by rectifier within one second ?

Options

A. 50
B. 100
C. 25
D. 150

Answer

A

Explanation

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, i.e.
`f_("out")=f_("in")`
So, pulses obtained in 1 s by half-wave rectifier will be 50.
