The Difference between ElectroStatic Charges & Electrostatic Discharges (ESD)

Desco Europe Blog

A question that comes up, again and again, is “Are ElectroStatic charges and ElectroStatic discharges different?” so we thought it’d be helpful for everyone to put together a blog post on the subject. So let’s get started:

ElectroStatic charges vs. ElectroStatic discharges

ElectroStatic charges and ElectroStatic discharges are different. All material can tribocharge (generate ElectroStatic charges). This is static electricity which is an electrical charge at rest. When an electrical charge is not at rest but discharges (i.e. ESD), problems can occur. All matter is constructed from atoms which have negatively charged electrons circling the atom’s nucleus which includes positively charged protons. The atom having an equal number of electrons and protons balances out having no charge.

Electrostatic charges are most commonly created by contact and separation; when two surfaces contact then separate, some atom electrons move from one surface to the other, causing an…
