Which electrode of a bipolar transistor corresponds to the source of a field-effect transistor?
- AEmitter
- BBase
- CDrain
- DCollector
Correct answer: A — Emitter. From the official ISED question bank, verified word for word.
Why
The Emitter is the correct match because it is the electrode that releases charge carriers into the transistor, just as the Source releases them in a field-effect transistor. The full explanation — and one for every question — is in Pro.
