Electronic Devices Question 23

Question: In a transistor in CE configuration, the ratio of power gain to voltage gain is

[J & K CET 2005]

Options:

A) a

B) b / a

C) ba

D) b

Show Answer

Answer:

Correct Answer: D

Solution:

For CE configuration voltage gain $= β \times R_{L} / R_{i}$

Power gain $= β^{2} \times R_{L} / R_{i}$

Therefore $\frac{Power gain}{Voltage gain} = β$
