Electronic Devices Question 18

Question: In the CB mode of a transistor, when the collector voltage is changed by 0.5 volt. The collector current changes by 0.05 mA. The output resistance will be

[Pb. PMT 2003]

Options:

A) 10 kW

B) 20 kW

C) 5 kW

D) 2.5 kW

Show Answer

Answer:

Correct Answer: A

Solution:

Here ΔVc=0.5V , Δic =0.05mA = 0.05 x 103 A

Output resistance is given by

Rout=ΔVcΔic=0.50.05×103=104Ω = 10kW.
