An element which is sometimes an insulator and sometimes a conductor is called a:

1. A N-type conductor
2. B P-type conductor
3. C semiconductor
4. D intrinsic conductor

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

Why

A semiconductor is a material like silicon that acts as an insulator under some conditions but allows electricity to flow like a conductor under others, depending on factors such as temperature or added impurities. The full explanation — and one for every question — is in Pro.
