The charge on capacitor of capacitance 15 μ F in the figure given below is

Options

  1. A60   μC
  2. B130   μC
  3. C260   μC
  4. D585   μC

Correct answer

A. 60   μC

Step-by-step solution

As we know, Q = C V Here all capacitors are connected in series. Thus, equivalent capacitance is C e q = 1 10 + 1 15 + 1 20 - 1 = 6 + 4 + 3 60 - 1 = 60 13   μF Therefore, charge Q = 60 13 × 13 = 60   μC . As the capacitors are connected in series, charge on each capacitor wil be same.
