$A$ diode is used as a/an

Explain the use of the junction diode as a half-wave rectifier by drawing a circuit and draw input and output waves.

$A$ 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 :.......$V$

In the circuit shown in the figure, determine the output waveform and the output d.c. level of $V_0$.

Which of the following circuits provides full-wave rectification of an $A.C.$ input?

In a rectifier circuit,the filter circuit:
