What is ESD?

Electrostatic discharge (ESD) is the release of static electricity when two objects come into contact.

If you have had a shock from a metal doorknob after walking across a carpet on a dry day or from the metal handle or bodywork of a car, you have experienced a static shock.

When clothes cling to each other after removing them from the dryer or your hair stands on end following vigorous combing with a nylon comb , it is caused by an electrostatic charge.

The most dramatic form of electrostatic discharge is the lightning in a thunderstorm.
