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 .
Electrotherapy treatment of a person with faradic electricity. Coined by Duchenne de Boulogne and named after Michael Faraday. [4] Franklinization Electrotherapy by charging a person to high voltage with static electricity. Named after Benjamin Franklin. [5] d'Arsonvalization Electrotherapy treatment of a person with high frequency electricity.
Small Van de Graaff generators are commonly used in science museums and science education to demonstrate the principles of static electricity. A popular demonstration is to have a person touch the high voltage terminal while standing on an insulated support; the high voltage charges the person's hair, causing the strands to stand out from the head.
Biefeld–Brown effect — Thought by the person who coined the name, Thomas Townsend Brown, to be an anti-gravity effect, it is generally attributed to electrohydrodynamics (EHD) or sometimes electro-fluid-dynamics, a counterpart to the well-known magneto-hydrodynamics. Bioelectrogenesis — The generation of electricity by living organisms.
A branch of the electronics industry deals with preventing static charge build-up and protecting products against electrostatic discharge. Notably, a combination of footwear with some sole materials, low humidity, and a dry carpet can cause footsteps to charge a person's body capacitance to as much as a few tens of kilovolts with respect to the ...
Friction is the least-used of the six methods of producing energy. If a cloth rubs against an object, the object will display an effect called friction electricity. The object becomes charged due to the rubbing process, and now possesses an static electrical charge, hence it is also called static electricity. There are two main types of ...
The order Gymnotiformes, of which the best-known example is the electric eel, detect or stun their prey via high voltages generated from modified muscle cells called electrocytes. [ 3 ] [ 4 ] All animals transmit information along their cell membranes with voltage pulses called action potentials , whose functions include communication by the ...
When they were first discovered, it was thought that their characteristic shapes might help to reveal the nature of positive and negative electric "fluids". In 1777, Lichtenberg built a large electrophorus to generate high-voltage static electricity through induction. After discharging a high-voltage point to the surface of an insulator, he ...
