Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge . The word "static" is used to differentiate it from current electricity , where an electric charge flows through an electrical conductor .
The human-body model emulates the action of a human body discharging static electricity, the machine model simulates static discharge from a machine, and the charged-device model simulates the charging and discharging events that occur in production processes and equipment. [citation needed]
The model is a simulation of the discharge which might occur when a human touches an electronic device. The HBM definition most widely used is the test model defined in the United States military standard, MIL-STD-883, Method 3015.9, Electrostatic Discharge Sensitivity Classification.
Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects.
An educational program at the Theater of Electricity, Boston Museum of Science demonstrates the world's largest air-insulated Van de Graaff generator, built by Van de Graaff in the 1930s. The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of ...
This method covers the full range of electromagnetics (from static up to high frequency) and optic applications and is the basis for commercial simulation tools: CST Studio Suite developed by Computer Simulation Technology (CST AG) and Electromagnetic Simulation solutions developed by Nimbic.
Ancient Greek philosopher Thales of Miletus described static electricity by rubbing fur on substances such as amber. 1600: English scientist William Gilbert coined the word electricus after careful experiments. He also explained the magnetism of Earth. 1660: German scientist Otto von Guericke invented a device that creates static electricity ...
Foam peanuts clinging to a cat's fur due to static electricity.The cat's fur becomes charged due to the triboelectric effect.The electric field of the charged fur causes polarization of the molecules of the foam due to electrostatic induction, resulting in a slight attraction of the light plastic pieces to the fur.
