Question

33. In a BJT, as the conductivity of the base region increases, the punch-through voltage (a) remains unaltered (b) increases (c) decreases (d) may increase or decrease​

Answer 1

Roughly, the emitter current of a BJT increases exponentially as the base-emitter voltage increases.

Answer 2

Answer of the given question

Explanation:

• The base-region occurs between the emitter & collector.

• The BJT (bipolar-junction-transistor) is a current-controlled electronic device mainly employed for the amplification & switching purpose.

• It comes with three terminals called base, collector & emitter.
• The small current at base side is used to control the large current at remaining terminals. Earlier BJTs were made up of germanium, but now a days BJT is made up of silicon.
