The capacitance of the capacitors C 1 , C 2 and C 3 are 4   μF , 6   μF and 12   μF respectively as shown, and the switch S remains closed for a long time. When the switch S is opened, which of the following statements will be correct about the current flowing through the battery B ?

Options

  1. Aa finite and constant current will flow
  2. Ba finite current will flow initially thatwill decrease exponentially with time
  3. Cno current will flow
  4. Dinformation is insufficient to predict

Correct answer

C. no current will flow

Step-by-step solution

Capacitors are already in steady state.
