For an ideal diode,in forward and reverse biased condition the resistance is respectively

The potential barrier of a $P-N$ junction is $0.5 \ V$. The thickness of the depletion layer is $5.0 \times 10^{-7} \ m$. Calculate the electric field.

If the voltage across the diode in the given circuit is $0.5 \ V$,then the current flowing through the circuit is ...... $mA$.

For diode $D_1$,the forward bias resistance is $20 \ \Omega$ and the reverse bias resistance is $600 \ \Omega$. For diode $D_2$,the forward bias resistance is $30 \ \Omega$ and the reverse bias resistance is $200 \ \Omega$. Find the equivalent resistance between $A$ and $B$ if $(i)$ $A$ is at a higher potential,and $(ii)$ $B$ is at a higher potential.

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

The forward biased diode connection is:
