Question

Three capacitors of 2 µF each are connected in series. The equivalent capacitance is

Accepted Answer

B. {'text': '2/3 µF', 'label': 'B'}

1. In series, 1/Cₑ = 1/C + 1/C + 1/C = 3/C.
2. Cₑ = C/3 = 2/3 µF.
3. Option (A) is the parallel result, so the trap is for students who mix the rules.
