$A$ $2V$ battery is connected across the points $A$ and $B$ as shown in the figure. Assuming that the resistance of each diode is zero in forward bias and infinity in reverse bias,the current supplied by the battery when its positive terminal is connected to $A$ is........$A$

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.....$mA$

The $I-V$ characteristic of a $P-N$ junction diode is shown in the figure. The approximate dynamic resistance of the $P-N$ junction when a forward bias of $1\;V$ is applied is.......$\Omega$.

$A$ semiconductor is damaged by a strong current due to:

$A$ diode having a potential difference of $0.5\, V$ across its junction,which does not depend on the current,is connected in series with a resistance of $20\, \Omega$ across a source. If $0.1\, A$ passes through the resistance,then what is the voltage of the source (in $, V$)?

The cause of the potential barrier in a $p-n$ junction diode is
