What term describes the most basic semiconductor component used to amplify?
- ATransistor
- BVaractor
- CP-N junction
- DDiode
Correct answer: A — Transistor. From the official ISED question bank, verified word for word.
Why
A transistor is the most basic semiconductor component designed specifically to amplify weak signals by using a small input to control a larger output current. The full explanation — and one for every question — is in Pro.
