PHY 102 Last Minute Prep Objective Question

Question

A 2-μF and a 1-μF capacitor are in series and charged. They store charges P and Q. When disconnected and charged separately with same battery, they have charges R and S. Then:
Options
A R > S > Q = P
B P > Q > R = S
C R > P = Q > S
Correct Answer
D R = P > S = Q
Correct Answer

Option C is the correct answer.

Detailed Explanation

In series, same charge P = Q. Separately, R = 2V, S = 1V, so R > S. Thus R > P = Q > S.

Hint

In series, charge is same. Separately, Q = CV.
