Five conduting parallel plates having area `A` and separation between them `d`, are placed as shown in the figure. Plate number `2` and `4` are connected wire and between point `A` and `B`, a cell of `emf E` is connected. The charge flown through the cell is

Five conducting parallel plates having area A and separation between them d, are placed as shown in the fig. Plate number 2 and 4 are connected with a conducting wire and between point A and B a cell of emf. .epsilon. is connected . The change flows through the cell is

A parallel plate capacitor having plate area A and separation between the plates d is charged to potential V .The energy stored in capacitor is ....???

Five identical metal plates each of area A are placed at equal separation d as shown in figure and are connected with conducting wires. The equivalent capacitance across points A and B is

Three identical metallic plates are kept parallel to one another at separations a & b as shown in figure. The outer plates are connected by a thin conducting wire and a charge Q is placed on the central plate. Find the charge on all the six sufaces.

A parallel plate capacitor is charged from a cell and then isolated from it. The separation between the plates is now increased
