What is the alpha of a bipolar transistor in common base configuration?
- A Forward current gain
- B Forward voltage gain
- C Reverse current gain
- D Reverse voltage gain
Correct answer: A — Forward current gain. From the official ISED question bank, verified word for word.
Why
Alpha measures how much the output current in a common base setup follows the input current, making it a forward current gain because the signal moves from emitter to collector. The full explanation — and one for every question — is in Pro.
