Description
Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and the flow of electrical current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.
In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics:
⁕electric charge: a property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields.
⁕electric current: a movement or flow of electrically charged particles, typically measured in amperes.
⁕electric field: an especially simple type of electromagnetic field produced by an electric charge even when it is not moving. The electric field produces a force on other charges in its vicinity. Moving charges additionally produce a magnetic field.
⁕electric potential: the capacity of an electric field to do work on an electric charge, typically measured in volts.
