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 because of the following, an electric charge, that is a property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields, electric current which is 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 for example there is no electric current. The electric field produces a force on other charges in its vicinity. Moving charges additionally produce a magnetic field. Electric potential is the capacity of an electric field to do work on an electric charge, typically measured in volts. Electromagnets are electrical currents generate magnetic fields, and changing magnetic fields generate electrical currents. Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth and eighteenth centuries. Practical applications for electricity however remained few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricity's extraordinary versatility as a means of providing energy means it can be put to an almost limitless set of applications which include...
