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 $ =\beta \times R _{L}/R _{i} $

Power gain $ ={{\beta }^{2}}\times R _{L}/R _{i} $

Therefore $ \frac{\text{Power gain}}{\text{Voltage gain}}=\beta $
