Electric Arc

An electric arc provides a demonstration of electric current.

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, staticelectricity, electromagnetic induction and 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:

In electrical engineering, electricity is used for:

Electrical phenomena have been studied on Terra since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries CE. Even then, 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 means it can be put to an almost limitless set of applications which include transport, heating and lighting.

Electrical power is now the backbone of modern Union industry.
