Quel est l'inverse de la résistance?
- ALa réactance
- BLa réluctance
- CLa perméabilité
- 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.
