Application of a forward biase to a `p-n` junction:

Options

A. increases the number of donors on the `n`-side
B. increases the electric field in the depletion zone
C. increases the potential difference across the depletion zone
D. widense the depletion zone

Answer

A

Explanation

When `p`-side of junction diode is connected to positive of battery and `n`-side to the negative, then junction diode is forward biased.

In this condition, more number of electrons enter in `n`-side from battery, thereby increasing the number of donor on `n`-side.
