The diode voltage is $0.5 \ V$ and the maximum power rating is $100 \ mW$. To obtain the maximum current in the circuit,the value of $R$ should be .......... $\Omega$.

The increase in the width of the depletion region in a $p-n$ junction diode is due to

In the circuit shown in the figure,the non-zero potential difference across diode $D_{1}$ and that across diode $D_{2}$ are equal. Are the diodes identical in characteristics? Explain.

$A$ waveform is applied to the following circuit. Assuming an ideal diode configuration and $R_1 = R_2$, which of the following output waveforms will be produced?

The current-voltage relation of a diode is given by $I = \left( {{e^{\frac{{1000V}}{T}}} - 1} \right) \, mA$,where the applied voltage $V$ is in volts and the temperature $T$ is in Kelvin. If a student makes an error of $\pm 0.01 \, V$ while measuring the voltage to obtain a current of $5 \, mA$ at $300 \, K$,then the error in the value of the current in $mA$ is.....$mA$

The cause of the potential barrier in a $p-n$ junction diode is
