Electronic Devices Question 4
Question: A transistor is used in common emitter mode as an amplifier. Then
[IIT-JEE 1998]
Options:
A) The base-emitter junction is forward biased
B) The base-emitter junction is forward biased
C) The input signal is connected in series with the voltage applied to the base-emitter junction
D) The input signal is connected in series with the voltage applied to bias the base-emitter junction
Show Answer
Answer:
Correct Answer: C,D
Solution:
The circuit of a CE amplifier is as shown below.
This has been shown to be an NPN transistor.
Therefore, base-emitter are forward biased, and input signal is connected between base and emitter.
