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 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.
