Question

(D) none of above
21. When an external battery is connected across the p-n junction diode, it is called
(A) earthing
(B) circuit
(C) biasing
(D) none of these

​

Answer 1

Biasing is the correct answer

Answer 2

Option “C” is correct i.e. biasing.

• The biasing may be forward or reverse bias.

• When the external battery is connected across the p-n junction diode, it is known as bias.

• If p is connected to the positive terminal and n to the negative terminal it is called forward bias.

• It p is connected to the negative terminal and n to the positive terminal then it is called negative biasing.
