Three equal capacitors, each of capacitance A, are connected in series. The effective capacitance (as seen by the source)
A) is 3 A.
B) is A/3.
C) is A.
D) cannot be determined (we need to know A).

Question

Quizplus · Accepted Answer

When capacitors are connected in series, the reciprocal of the total capacitance is the sum of the reciprocals of the individual capacitances. For three capacitors each of capacitance A, the effective capacitance is 1/(1/A + 1/A + 1/A) = A/3.
