What term describes the most basic semiconductor component used to amplify?

  1. ATransistor
  2. BVaractor
  3. CP-N junction
  4. 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.
