Quel terme décrit le taux auquel l'énergie électrique est utilisée?
- ALe courant

Correct answer: D — La puissance. Question tirée de la banque officielle d'ISDE.
Why
Power is the correct term because it measures how fast electrical energy is being used or converted into work, much like how a light bulb's brightness depends on the rate of energy consumption. The full explanation — and one for every question — is in Pro.
