An Introduction to Static Electricity

Static Electricity is electricity at rest or the accumulation of electric charge, as opposed to an electric current which is the movement of electricity.The flow or movement of people and/or materials in and through the environment causes separation and therefore static electricity. A familiar example is when a person walks across a carpeted floor. Static Electricity is generated simply by the contact and separation of the soles of shoes from the carpeted floor. ESD occurs when the electrostatic charge is transferred from a material that carries the charge to an electrostatic sensitive device. In the example above this ESD is the shock felt after walking across the carpeted floor and then touching a door knob. It is this ESD, which comes in varying degrees, that can be most damaging to electrical devices and other industrial, commercial and consumer products.
