Two circuits (a) and (b) have charged capacitors of capacitance C, 2C and 3C with open switches. Charges on each of the capacitor are as shown in the figures. On closing the switches Circuit (a) Circuit (b)

Options

  1. ANo charge flows in (a) but charge flows from R to L in (b)
  2. BCharges flow from L to R in both (a) and (b)
  3. CCharges flow from R to L in (a) and from L to R in (b)
  4. DNo charge flows in (a) but charge flows from L to R in (b)

Correct answer

C. Charges flow from R to L in (a) and from L to R in (b)

Step-by-step solution

Charge (or current) always flows from higher potential to lower potential. Potential = Charge Capacitance
