Two capacitors A and B with capacities are charged to potential difference of respectively. The plates of the capacitors are connected as shown in the figure. The upper plate of A is positive and that of B is negative. An uncharged capacitor of capacitance C and falls on the free ends to complete circuit, then
Charge on positive plate of A is Charge on negative plate of B is When d plate of capacitor C is connected with the plate of A, then the total charge of (d, a) plate system will be (conservation of charge).
