If you wire two 24-microfarad capacitors in parallel, what is the capacity of the combination?
- A 4 microfarads
- B 48 microfarads
- C 12 microfarads
- D 96 microfarads
Correct answer: B — 48 microfarads. From the official ISED question bank, verified word for word.
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.
