The $PN$ junction diode is used as:

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

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

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

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 efficiency of the rectifier is approximately ...... $\%$.
