Three identical fixed metal plates are arranged in the air at equal distances d from each other The area of each of the plates equals A The plate 1 has charge Q while plates 2 and 3 are not charged and are connected through a key K to the inductor L The distance between the plates is small compared with their size The ohmic resistance of the coil can be neglected A Just before the switch K is closed the charge on right surface of plate 2 is Q 2 B Just before the switch K is closed the charge on right surface of plate 3 is Q 2 e After the switch K is closed the maximum current in the circuit is Q Lefed Q d 2 LE A D After the switch K is closed the maximum current in the circuit is d L A L oooooo
