Question

p-n junction is said to be forward biased, when 

(a) the positive pole of the battery is joined to the p-semiconductor and negative pole to the n-semiconductor

(b) the positive pole of the battery is joined to the n-semiconductor and p-semiconductor 

(c) the positive pole of the battery rs connected to n-semiconductor and p-semiconductor 

(d) mechanical force is applied in the forward direction.

Answer 1

The correct option is (a) the positive pole of the battery is joined to the p-semiconductor and negative pole to the n-semiconductor.

Explanation:

For forward biasing of p-n junction, the positive terminal of external battery is to be connected to p semiconductor and negative terminal of battery to the n semiconductor.
