Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
A transistor is used in common emitter mode as an amplifier. Then: (1) the base-emitter junction is forward biased (2) the base-emitter junction is reverse biased (3) the input signal is connected in series with the voltage applied to bias the base-collector junction (4) the input signal is connected in series with the voltage applied to the base-emitter junctionA) 1 and 2 are correct
B) 2 and 3 are correct
C) 1 and 4 are correct
D) 1, 2 and 3 are correct
Correct Answer: C
Solution :
While using a transistor as a common-emitter amplifier, the emitter-base junction is forward biased and the signal to be amplified is connected in emitter-base junction.You need to login to perform this action.
