On which of the following does the barrier potential of a $P-N$ junction diode $NOT$ depend?

The current-voltage relation of a diode is given by $I = (e^{1000V/T} - 1) \; mA$,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 $300 \; K$,what will be the error in the value of the current in $mA$?

In the circuit shown in the figure,determine the voltage $V_0$ for the circuit network.

What is the cause of the formation of the depletion layer in a $P-N$ junction?

What is a depletion layer? What is the order of its thickness?

The forward resistance of the diode is zero and the reverse resistance is infinite. When the positive terminal of a $2 \ V$ battery is connected to point $A$ and the negative terminal to point $B$,what current will flow through the circuit (in $A$)?
