If two equal-value capacitors are connected in parallel, what is their total capacitance?
- ATwice the value of one capacitor
- BHalf the value of either capacitor
- CThe value of one capacitor times 4
- DThe value of one capacitor divided by 4
Correct answer: A — Twice the value of one capacitor. From the official ISED question bank, verified word for word.
Why
When you connect two equal capacitors side by side in parallel, you effectively double the total plate area available to store electric charge, which directly doubles the ability to hold that charge. The full explanation — and one for every question — is in Pro.
