Question

The battery connection required to forward bias a PN junction is:
Options
A +ve terminal to P and -ve terminal to N
Correct Answer
B -ve terminal to P and +ve terminal to N
C -ve terminal to P and -ve terminal to N
D none of the above
Correct Answer

Option A is the correct answer.

Detailed Explanation

For a PN junction to be forward biased, the positive terminal of the battery must be connected to the P-type material and the negative terminal to the N-type material. This reduces the depletion region and allows current to flow.

Hint

Consider how the external voltage should affect the depletion region to allow current flow.
