Electrostatic discharge (ESD) is a quick transfer of an electrostatic charge. ESD happens between two objects of differing electrostatic charge. The degree of ESD can vary greatly from a minor tickle to something more devastating. Not only can it harm you, but it can harm any electrical components that helped create the charge. When working with electrical components, it is very important to stay grounded to avoid getting shocked and shorting out the equipment. One way to do this is to create an anti-static wristband, worn around the wrist and constantly connected to a grounded component.
