Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of
Electricity is invisible, but it can yield visually observable phenomena, shown here with the flash of lightning and various forms of electric light in the buildings.
A fictional portrait of Thales, the earliest known researcher into electricity
Benjamin Franklin conducted extensive research on electricity in the 18th century, as documented by Joseph Priestley (1767) History and Present Status of Electricity, with whom Franklin carried on extended correspondence.
Michael Faraday's discoveries formed the foundation of electric motor technology.
Electrostatics

Electrostatics is a branch of physics that studies slow-moving or stationary electric charges on macroscopic objects where quantum effects can be neglected. Under these circumstances, the electric fie
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. This effect is also the cause of static cling in clothes.
