Consider the junction diode as ideal. The value of current flowing through $AB$ is

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.....$mA$

As shown in the figure,a diode is connected to an external resistor. Assume that the barrier potential developed in the diode is $0.5 \ V$. Find the value of the current in the circuit in milliamperes. (in $mA$)

$A$ junction diode has a resistance of $25 \Omega$ when forward biased and $2500 \Omega$ when reverse biased. The current in the diode, for the arrangement shown, will be

Assuming an ideal diode,find the current through the $1 \Omega$ resistance in the circuit shown in the figure.

When and why is a $p-n$ junction called forward biased? Describe the changes that occur under such bias.
