Electronic Devices Question 8

Question: For a transistor, the current amplification factor is 0.8. The transistor is connected in common emitter configuration. The change in the collector current when the base current changes by 6 mA is

[Haryana CET 1991]

Options:

A) 6 mA

B) 4.8 mA

C) 24 mA

D) 8 mA

Show Answer

Answer:

Correct Answer: C

Solution:

a = 0.8
β=0.8(10.8) =4

Also β=ΔicΔib

Δic=β×Δib = 4 x 6 = 24mA.
