When a forward bias is applied to a $p-n$ junction,it . . . . . . .

In a $PN$-junction diode,the reverse saturation current is ${10^{-5}} \ A$ at $27^\circ C$. Calculate the forward current for a voltage of $0.2 \ V$. Given: $[\exp(7.62) = 2038.6, \ k_B = 1.4 \times {10^{-23}} \ J/K, \ e = 1.6 \times {10^{-19}} \ C]$.

Avalanche breakdown is due to

In the circuit,if the forward voltage drop for the diode is $0.5 \,V$,the current will be.....$ mA$

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:
