Electrostatics
Electrostatics
Electrostatics (pronunciation: /ɪˌlɛktrəʊˈstatɪks/) is a branch of physics that studies electric charges at rest.
Etymology
The term "electrostatics" is derived from the Greek word "ēlektron" meaning "amber", and the English suffix "-statics". Amber, when rubbed, can attract light objects, a phenomenon known as static electricity.
Definition
Electrostatics involves the buildup of charge on the surface of objects due to contact with other surfaces. This is a result of the different materials' ability to attract or repel electrons. Electrostatics is responsible for the functioning of many common objects, from balloons sticking to walls to the operation of capacitors in electronic devices.
