If a full wave rectifier circuit is operating from $50 \,Hz$ mains, the fundamental frequency in the ripple will be (in $\,Hz$)

The frequency of a given $AC$ signal is $N \ Hz$. When it is connected to a half-wave rectifier,the number of output pulses given by the rectifier in $1 \ s$ is:

$A$ diode is used as a/an

In a rectifier circuit,the filter circuit:

$A$ $PN$ junction diode is used as:

If a square signal of $10 \ V$ (varying from $+5 \ V$ to $-5 \ V$) is applied to a $P-N$ junction diode as shown,the output signal across $R_L$ will be:
