... The balloon has a net charge as a result of being rubbed. When the balloon is brought near a wall, the net charge on the balloon moves electrons around in the wall. As a result, a small region near the balloon has a net charge of opposite sign than the balloon. The overall wall is still electrically ...

The Nature of Light (PowerPoint)
... When a light photon with enough energy strikes the thin metal sheet an electron is ejected from the surface of the metal and attracted towards the positive plate. The electron then moves through the wires towards the positive side of the battery. As it moves through the ammeter (A), it causes the ne ...
