Electrostatic Discharge (ESD)

The fundamental aspect of matter that permits the flow of electricity is the existence of free electrons in that matter. The electrical resistance of a material is defined by how many free electrons exist in the material. Metals, for example, have many free electrons, so it is relatively easy to generate a current flow in them. Insulators, on the other hand, have few free electrons, so current flow is proportionally lower. An attribute of insulators is that they do not allow redistribution of electrical charge across their entire surface, so they can permit local electrical charge to build up. This is static electricity and leads to electrostatic discharge (ESD) damage to electronic devices.
