If $\mathrm{p}-\mathrm{n}$ junction diode is reverse biased then

If $\mathrm{p}-\mathrm{n}$ junction diode is reverse biased then
  1. potential barrier decreases.
  2. width of the depletion layer decreases.
  3. electrical conduction is possible.
  4. width of the depletion layer increases.

Solution

When p-n junction is reverse biased, the depletion region is increased i.e., the potential barrier increased.
