Options

  1. A12 C
  2. B16 C
  3. C14 C
  4. D11 C

Correct answer

A. 12 C

Step-by-step solution

Two capacitors of capacities 2 F and 4 F are connected in parallel. A third capacitor of 6 F capacity is connected in series with this combination. A battery of 12 ~V is connected across this combination. The charge on 2 F capacitor is 12 C . Explanation: The circuit diagram of given situation is as shown below The equivalent capacitance of 2 F and 4 F capacitors connected in parallel Is C_ e q =2+4=6 F The circuit now becomes As, both the capacitors are of the same capacitance, so the potential of 12 ~V is equally
