Question

A p-n junction is forward biased. Describe the movement of the charge carriers which produce current in it.

Answer 1

In forward bias, the p-side is linked to the positive terminal and the n-side to the negative terminal of a battery.

1. Electrons from the n-side move towards the p-side, and holes from the p-side move towards the n-side.
2. This movement permits current to flow by reducing the depletion region.
