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

$A$ diode is used as a/an

$A$ 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:

Explain the use of a junction diode as a full-wave rectifier by drawing a circuit diagram and show the input and output waveforms.

What is rectification and rectifier? Why is a $p-n$ junction diode used as a rectifier?

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 $10 \ \Omega$. Calculate the peak,average,and $rms$ values of the load current,respectively.
