The electrodes of a semiconductor diode are known as:
- A collector and base
- B cathode and drain
- C anode and cathode
- 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.
