Electronic Devices Question 297

Question: In a common emitter transistor, the current gain is 80. What is the change in collector current, when the change in base current is 250 mA

[CBSE PMT 2000]

Options:

A) 80 x 250 mA

B) (250 - 80) mA

C) (250 + 80) mA

D) 250/80 mA

Show Answer

Answer:

Correct Answer: A

Solution:

Current gain β=ΔicΔib
Δic=β×Δib = 80 x 250 mA.
