Question

With the help of circuit diagrams, briefly explain the forward biasing of a p-n junction diode.

Answer 1

The positive terminal of the power supply is connected to the p-type material (anode), and the negative terminal is connected to the n-type material (cathode). In this setup, the positive terminal of the battery is connected to the p-end of the crystal and the negative terminal to the n-end, creating an external electric field E that opposes the internal field E_i, as illustrated in the diagram. The external field E is significantly stronger than the internal field E_i.
