Assuming the diodes to be of silicon with forward resistance zero, the current $I$ in the following circuit is.......$mA$

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

The forbidden energy gap of $Ge$ is $0.75 \ eV$. The maximum wavelength of incident photon radiation that can generate an electron-hole pair in a $Ge$ semiconductor is ........... $\mathring{A}$.

Find the current through the $1\,\Omega$ resistance in the given circuit.

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.....$mA$

In the figure shown, if the diode forward voltage drop is $0.2 \, V$, the voltage difference between $A$ and $B$ is (in $V$)
