Which electrode of a bipolar transistor corresponds to the drain of a field-effect transistor?
- A Source
- B Emitter
- C Collector
- D Base
Correct answer: C — Collector. From the official ISED question bank, verified word for word.
Why
In a bipolar transistor, the collector gathers charge carriers much like a drain pulls current away in a field-effect transistor. The full explanation — and one for every question — is in Pro.
