Quel est l'inverse de la résistance?

  1. ALa réactance
  2. BLa réluctance
  3. CLa perméabilité
  4. DLa conductance

Correct answer: D — La conductance. Question tirée de la banque officielle d'ISDE.

Why

Conductance measures how easily electricity flows through a material, making it the exact opposite of resistance, which measures how much a material blocks that flow. The full explanation — and one for every question — is in Pro.
