Question

The bipolar junction transistor simply called the transistors is a ……. terminal solid state device.

(A) two

(B) three

(C) four

(D) non​

Answer 1

The bipolar junction transistor simply called the transistors is a three-terminal solid-state device.

Option (b) is correct.

Explanation:

• A bipolar junction transistor consists of two p-n junctions.
• It comes with three terminals across the transistor which are emitter, collector, and a base.
• Electrons and holes of bipolar junction transistor carry the charge across it.
• whenever a signal is applied in it, the p-n junction amplifies the signal.
• The amplification process in bipolar junction transistor tales place without any power supply.
