If the output frequency of a full-wave rectifier is $100 \text{ Hz}$,then the input frequency will be . . . . . . . (in $\text{ Hz}$)

$A$ 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.

$A$ half-wave rectifier is used to supply $100 \, V$ $dc$ to a load of $800 \, \Omega$. The diode resistance is $200 \, \Omega$. The $ac$ voltage required is :.......$V$

$A$ sinusoidal voltage of peak value $200\,V$ is connected to a diode and resistor $R$ in the circuit shown,so that half-wave rectification occurs. If the forward resistance of the diode is negligible compared to $R$,the rms value of voltage across $R$ is approximately (in volt):

In comparison to a half-wave rectifier,the full-wave rectifier gives lower

In a rectifier circuit,the filter circuit:
