Semiconducting Devices Question 101
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 reverse 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 collector junction
Show Answer
Answer:
Correct Answer: C
Solution:
The circuit of a CE amplifier is as shown below.
This has been shown a NPN transistor.
Therefore base emitter are forward, biased and input signal is connected between base and emitter.
