The Physics Classroom

It could be said that the Styrofoam has served to polarize the aluminum plate - i.e., to separate its positive charge from its negative charge. While there may be a separation of charge within the aluminum plate, the overall charge of the plate is zero. Once the aluminum plate is touched, electrons move from the aluminum plate to the ground. It is at this instant that the aluminum plate acquires an overall positive
