The ratio of forward bias resistance to reverse bias resistance of a $P-N$ junction is approximately .......

In forward biasing of the $p-n$ junction:

$P-N$ junction is said to be forward biased,when

In $P-N$ junction,the barrier potential offers resistance to

In a $p-n$ junction diode,an electric field of magnitude $2 \times 10^5 \ V/m$ exists in the depletion region. $A$ particle with charge $-3e$ can diffuse from $n$-side to $p$-side,if it has a minimum kinetic energy of $0.6 \ eV$. The width of the depletion region of the $p-n$ junction is: (in $nm$)

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