![]() In contrast, an electronic component that is electrostatic discharge sensitive (ESDS), such as a hard drive, can be damaged by a 10 V ESD event. As an example, someone walking across a carpet can generate 1500 V of static electricity in relative humidity (RH) of 65% to 90% and 35,000 V of static electricity in RH of 10% to 20%. Besides triboelectric charging, other less common sources of static electricity include induction, ion bombardment, and contact with another charged object.Īlthough static electricity is measured in coulombs, engineers often focus on evaluating the electrostatic potential between materials, which is measured in volts and depends on the electric charges, their spatial arrangement and the distance between the materials. The amount of electric charge created by triboelectric charging depends on many factors, including contact area, properties of the materials, how quickly the materials are separated, and relative humidity. You feel a shock as the static electricity from your body discharges in an ESD event through a metal doorknob, which acts as a conductor. For example, when you walk across a carpeted floor, the interaction between the carpet and your shoes causes the carpet to lose electrons, making it positively charged, and your shoes to gain electrons, making them negatively charged. Static electricity, formally referred to as electrostatic charge, is most commonly created by the contact and separation of materials in a process known as triboelectric charging.
