electrostatic force - Physics | Oregon State University
... Coulomb’s Law speaks only of the magnitude of the electrostatic force. What about its direction? Gravitational force is always attractive. But with electrostatic force, the direction depends on the charge types: Opposite charge types attract; like charge types repel. Electrostatic forces are vector ...

CONDUCTORS AND INSULATORS
... We define a conductor as a material in which charges are free to move over macroscopic distances—i.e., they can leave their nuclei and move around the material. An insulator is anything else. In an insulator the charge distribution in an atom may change, but the charges do not leave their nuclei. Wh ...

Static electricity
.jpg?width=300)
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.A static electric charge is created whenever two surfaces contact and separate, and at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shock–more specifically, an electrostatic discharge–is caused by the neutralization of charge.
