The alpha of a bipolar transistor is specified for what configuration?
- A Common base
- B Common collector
- C Common gate
- D Common emitter
Correct answer: A — Common base. From the official ISED question bank, verified word for word.
Why
Alpha measures how well a bipolar transistor passes current when the base is shared between the input and output, a setup known as the Common base configuration. The full explanation — and one for every question — is in Pro.
