Electricity is a form of energy and it occurs in nature, so it wasn’t “Invented”. As to who discovered it, many misconception abound, some give credit to Benjamin Franklin for discovering electricity but his experiments only helped establish the connection between lightning and electricity.

The truth about the discovery of electricity is a bit complex; it actually goes back more than two thousand years ago. In 1831 electricity became viable for use in technology when Michael Faraday created the electric dynamo (a crude power generator) which solved the problem of generating electric current in an ongoing and practical way.

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 lighting, static electricity, electromagnetic induction and electrical current. In addition, electricity permits the creation and reception of electro-magnetic radiation such as radio waves.

Electrical phenomena have been studied since antiquity though progress in theoretical understanding remained slows until the 17th and 18th centuries.

Even then, practical applications for electricity were few and it would not be until the late 19th 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 means it can be put to an almost limitless set of applications which include transport, heating, lighting communications and computation. Electrical power is now the backbone of modern industrial society.

In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics.

1. Electric Charge: A property of some substance particles, which determines their electromagnetic interaction. Electricity charged matter is influenced by and produces electromagnetic fields.

2. Electric Field (set electrostatics): An especially simple type of electromagnetic field produced by an electric charge even when it isn’t moving. (i.e, there is no electric charge). The electric field produces a force on other charges in its vicinity.

3. Electric Potential: The capacity of an electric field to do work on an electric charge, typically measures in volts.

4. Electric Current: A movement or flow of electrically charged particles, typically measured in amperes.

5. Electromagnetic: Moving charges produces a magnetic field. Electrical currents generate magnetic field and changing magnetic field generate electrical currents.
