When the transistor is used as an amplifier

A

Emitter - base junction must be reverse biased, Collector - base junction must be forward biased.

B

Emitter - base junction must be forward biased, Collector - base junction must be forward biased.

C

Emitter - base junction must be reverse biased, Collector - base junction must be reverse biased.

D

Emitter - base junction must be forward biased, Collector - base junction must be reverse biased.

Text Solution

Verified by Experts

The correct Answer is:
