sir in redistribution when the battery is disconnected the charge remains constant isn't it. But when we connect another capacitor considering an uncharged capacitor, after some instant the potential of both became same for that condition there should occur a charge transmission from charged capacitor to uncharged capacitor isn't so in that condition the constant charge of first capacitor changes sir my dought is this whether it is saying that the the total charge of the system remains constant or is this is only for the first capacitor.
