Normally, a capacitor is connected across the output terminals of a rectifier to

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

The output form of a full wave rectifier is

In a half-wave rectifier using a $PN$ junction diode,the input voltage has an amplitude of $25 \ V$ and a frequency of $50 \ Hz$. No filter is used,and the load resistance is $1000 \ \Omega$. The forward resistance of the diode is $10 \ \Omega$. Calculate the peak,average,and $rms$ values of the load current,respectively.

Which of the following circuits provides full wave rectification of an $ac$ input?

Statement-$I$: To get a steady $DC$ output from the pulsating voltage received from a full wave rectifier,we can connect a capacitor across the output parallel to the load $R_L$.
Statement-$II$: To get a steady $DC$ output from the pulsating voltage received from a full wave rectifier,we can connect an inductor in series with $R_L$.
In the light of the above statements,choose the most appropriate answer from the options given below:
