In the following circuit of $PN$ junction diodes $D_1, D_2$ and $D_3$ are ideal,then the current $i$ is:

When a $p-n$ junction diode is reverse biased,then the width of the depletion layer will

Find the value of $V_{AB}$ in the given circuit.

The barrier potential of a $P-N$ junction diode does not depend on:

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 $mA$?

If the diodes are ideal in the circuit given below,then the current through the cell is (in $A$)
