The electrical circuit used to get smooth $dc$ output from a rectifier circuit is called

Select the correct statement.

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

$A$ full-wave rectifier provides a load of $1 \ k\Omega$. The diode is supplied with an $a.c.$ voltage of $220 \ V_{rms}$. If the diode resistance is neglected,the average $d.c.$ voltage and average $d.c.$ current are respectively:

If the frequency of the input voltage is $50 \,Hz$, applied to a $(a)$ half-wave rectifier and $(b)$ full-wave rectifier, what is the output frequency in both cases, respectively?

The output sinusoidal current versus time curve of a rectifier is shown in the figure. The average value of output current in this case is
