Two circuits (a) and (b) have charged capacitors of capacitance C,...

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 Two circuits (a) and (b) have charged capacitors of capacitance C, 2C and 3C with open switches. Charges on each of the
Two circuits (a) and (b) have charged capacitors of capacitance C, 2C and 3C with open switches. Charges on each of the
Circuit (a) Circuit (b)

Options

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

Correct answer

C. Charges flow from RR to LL in (a) and from LL to RR in (b)

Step-by-step solution

Charge (or current) always flows from higher potential to lower potential. Potential = Charge  Capacitance =\frac{\text{ Charge }}{\text{ Capacitance }}
