Question

When two identical parallel–plate capacitors are connected in series, which of the following is true of the equivalent capacitance?

(A) It depends on the charge on each capacitor.

(B) It depends on the potential difference across both capacitors.

(C) It is larger than the capacitance of each capacitor.

(D) It is smaller than the capacitance of each capacitor.

(E) It is the same as the capacitance of each capacitor.

Answer 1

The correct option is: (D) It is smaller than the capacitance of each capacitor.

Explanation:

In series, the equivalent capacitance is calculated using reciprocals, like resistors in parallel. This results in an equivalent capacitance smaller than the smallest capacitor.
