$A$ $220 \,V$ $AC$ supply is connected between points $A$ and $B$ as shown in the figure. What will be the potential difference $V$ across the capacitor?

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:

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

In a full-wave rectifier circuit without a filter,the output current is
