When the transistor is used as an amplifier
- A Emitter-base junction must be reverse biased, Collector-base junction must be forward
- 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
Answer & Solution
Correct Answer
(D) Emitter-base junction must be forward biased, Collector-base junction must be reverse biased
Step-by-step Solution
Detailed explanation
To use a transistor as an amplifier, its input must be forward biased and output must be reversed biased. So, emitter-base junction must be forward biased and collector-base junction must be reverse biased.
