For the circuit shown in the figure,what will be the voltage waveform across the diode? Assume the diode is ideal.

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

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 $10 \ \Omega$. The ripple factor is:

The process by which $ac$ is converted into $dc$ is known as

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 $10 \ \Omega$. The $d.c.$ power output and $a.c.$ power input are respectively:

$A$ 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 voltage (in volt) across $R$ is approximately:
