Si vous branchez deux condensateurs de 24 microfarads en parallèle, quelle est la capacité de la combinaison?
- A96 microfarads
- B4 microfarads
- C48 microfarads
- D12 microfarads
Correct answer: C — 48 microfarads. Question tirée de la banque officielle d'ISDE.
Why
When you connect capacitors in parallel, you are effectively joining their storage plates to create a larger surface area, which adds their individual capacities together. The full explanation — and one for every question — is in Pro.
