What is the beta of a bipolar transistor?
- A The change of collector current with respect to emitter current
- B The change of base current with respect to gate current
- C The change of collector current with respect to base current
- D The change of base current with respect to emitter current
Correct answer: C — The change of collector current with respect to base current. From the official ISED question bank, verified word for word.
Why
Beta measures how much the collector current changes when you tweak the base current in a bipolar transistor. The full explanation — and one for every question — is in Pro.
