The electrodes of a semiconductor diode are known as:

  1. A collector and base
  2. B cathode and drain
  3. C anode and cathode
  4. D gate and source

Correct answer: C — anode and cathode. From the official ISED question bank, verified word for word.

Why

A semiconductor diode has two main connection points called the anode and the cathode, which control the direction of electrical flow much like a one-way valve. The full explanation — and one for every question — is in Pro.
