Document Summary
Semiconductors can be either conductors and or heat. Charges are fixed and cannot more insulators switch by applying small voltage or shine light on them transistor. If there is then it is on the surface. I the charges will move but they will move far away from each other the charges stays where they were. If you place an excess charge on the surface of an insulator it stays there until you remove it. Positive ions are fixed on lattice structure and cannot move. If electric conductors typically reflect light and are thus shiny. Also conduct heat well you add excess charges to a conductor they move freely until they are furthest apart from each other. Displacement of pointer is roughly proportional to charge on. Grounding : when you put all the negative charge into the ground ( of earth ) changes the angle the of rod. Charging by contact transferring charge from one object to another by touching it.
