$A$ half-wave rectifier provides a load current of $1 \ k\Omega$. The input voltage is $220 \ V$. Neglecting the diode resistance,the value of the ripple voltage $(rms)$ is .... $V$.

The $PN$ junction diode is used as:

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:

The input a.c. voltage of frequency $60 \,Hz$ is applied to a half-wave rectifier and also to a full-wave rectifier. The output frequency in the case of the half-wave rectifier and that in the case of the full-wave rectifier is respectively:

$A$ diode detector is used to detect an amplitude modulated wave of $60\%$ modulation by using a condenser of capacity $250\, pF$ in parallel with a load resistance $100\, k\Omega$. Find the maximum modulated frequency which could be detected by it.
