In the circuit given below,the value of the current is

What is the current flowing through the given circuit? $A$ given diode is an ideal diode.

In the middle of the depletion layer of a reverse-biased $PN$ junction,the

$A$ potential barrier of $0.50 \ V$ exists across a $P-N$ junction. If the depletion region is $5.0 \times 10^{-7} \ m$ wide,the intensity of the electric field in this region is:

In the given figure,a diode $D$ is connected to an external resistance $R = 100 \,\Omega$ and an $e.m.f.$ of $3.5 \,V$. If the barrier potential developed across the diode is $0.5 \,V$,the current in the circuit will be ........ $mA$.

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 $mA$?
