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 electrical current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.
Electricity
The electricity is filled with our lives, the insulator is one main part of transmission lines made of porcelain and polymer, also known as porcelain insulator and polymer insulator.
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 field (see electrostatics): an especially simple type of electromagnetic field produced by an electric charge even when it is not moving (i.e., there is no electric current). The electric field produces a force on other charges in its vicinity.
◆ Electric potential: the capacity of an electric field to do work on an electric charge, typically measured in volts.
◆ Electric current: a movement or flow of electrically charged particles, typically measured in amperes.
◆ Electromagnets: Moving charges produce a magnetic field. Electrical currents generate magnetic fields, and changing magnetic fields generate electrical currents.
