If the forward voltage in a semiconductor diode is doubled,the width of the depletion layer will

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.....$mA$

Which of the following graphs is correct for a $P-N$ junction? (When the $P-N$ junction is forward biased.)

The reverse biasing in a $PN$ junction diode

The resistance of a germanium junction diode whose $V-I$ characteristic is shown in the figure is ........ $k\Omega$ $(V_k = 0.3 \, V)$.

For an ideal diode,in forward and reverse biased condition the resistance is respectively
