For a transistor to be used as an amplifier its input and output regions should be biased respectively in:
- A Forward and reverse biasing
- B Forward and forward biasing
- C Reverse and forward biasing
- D Reverse and reverse biasing
Answer & Solution
Correct Answer
(A) Forward and reverse biasing
Step-by-step Solution
Detailed explanation
To act as an amplifier, a transistor needs to operate in its active region. This is achieved by forward biasing the input (emitter-base) junction and reverse biasing the output (collector-base) junction A) Forward and reverse biasing
