Un élément qui est tantôt un isolant et, tantôt, un conducteur s'appelle :

  1. Aun conducteur de type N
  2. Bun conducteur de type P
  3. Cun semi-conducteur
  4. Dun conducteur intrinsèque

Correct answer: C — un semi-conducteur. Question tirée de la banque officielle d'ISDE.

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.
