What is the current through the battery in the circuit shown below (in $\text{A}$)?

In an experiment,the saturation in the plate current in a diode is observed at $240\,V$. But a student still wants to increase the plate current. It can be done,if

If the forward voltage in a diode is increased,the width of the depletion region $\qquad$ .

$A$ source voltage of $8V$ drives the diode in the figure through a current-limiting resistor of $100 \Omega$. Then the magnitude of the slope of the load line on the $V-I$ characteristics of the diode is

In the given circuit,the input voltage $V_{\text{in}}$ is shown in the figure. The cut-in voltage of the $p-n$ junction diode ($D_{1}$ or $D_{2}$) is $0.6\,V$. Which of the following output voltage $(V_{0})$ waveforms across the diode is correct?

$A$ $P-N$ junction has a potential barrier of $0.5 \ V$. If the depletion region is $5 \times 10^{-7} \ m$ wide,what will be the intensity of the electric field in this region?
