When considering the material between source and drain, what are two basic types of field-effect transistors (FET)?

  1. ASilicon and germanium
  2. BGallium and arsenide
  3. CN channel and P channel
  4. DNPN and PNP

Correct answer: C — N channel and P channel. From the official ISED question bank, verified word for word.

Why

Field-effect transistors are sorted by the type of charge carriers flowing between the source and drain, which creates either an N channel or a P channel. The full explanation — and one for every question — is in Pro.
