For the given electric voltage signal,the $dc$ value is......$V$.

In a half-wave rectifier, an $AC$ input source of frequency $50 \,Hz$ is used. The fundamental frequency of the output is: (in $\,Hz$)

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

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

$A$ 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):

If an alternating voltage is applied across a $p-n$ junction diode in series with a load,then:
