alleryTwo capacitors of 4 µF and 6 µF are connected in parallel and charged by a 10 V battery. The total charge stored is
A24 µC
B60 µC
C40 µC
D100 µC
Answer & Solution
Correct answer: D. 100 µC
1. Parallel ⇒ Cₑ = 4 + 6 = 10 µF.
2. Q = Cₑ V = 10 × 10 = 100 µC.
3. Distractors come from using just one of the capacitors, or the series formula.
