The width of the depletion layer is approximately .......

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.....$mA$

As shown in the figure,a diode is connected to an external resistor. Assume that the barrier potential developed in the diode is $0.5 \ V$. Find the value of the current in the circuit in milliamperes. (in $mA$)

When a forward bias is applied to a $p-n$ junction,it

In the diodes shown in the diagrams,which one is reverse biased?
