What is the charge on 15 F in the circuit given?

Options

  1. A230 C
  2. B260 C
  3. C130 C
  4. D160 C

Correct answer

C. 130 C

Step-by-step solution

From the given circuit diagram, the 15 F and 30 F capacitors are connected in series. The equivalent capacitance of this series branch is: C_s = 15 30 15 + 30 = 450 45 = 10 F This series branch is connected directly across the 13 V battery. Therefore, the potential difference across the series combination is 13 V . The charge Q on this series branch is given by: Q = C_s V = 10 F 13 V = 130 C In a series circuit, the charge on each capacitor is the same. Thus, the charge on the 15 F capacitor is equal to the total c
