While this could be at infinity, a much more useful reference is the Earth itself, which is assumed to be at the same potential everywhere. Their work was greatly expanded upon by Michael Faraday in Electricity use outside the OECD is dominated by industrial demand which accounts for half of consumption.
To begin to explain what electricity is we need to zoom way in, beyond the matter and molecules, to the atoms that make up everything we interact with in life. An electric field is created by a charged body in the space that surrounds it, and results in a force exerted on any other charges placed within the field.
This concept was introduced by Faraday,  whose term ' lines of force ' still sometimes sees use.
This is a copper atom diagram: 29 protons in the nucleus, surrounded by bands of circling electrons. In its balanced state, copper has 29 protons in its nucleus and an equal number of electrons orbiting around it.
Economics of generation and production of electricity[ edit ] See also: Cost of electricity by source and Electricity pricing The selection of electricity production modes and their economic viability varies in accordance with demand and region.
For that, we need to understand electric fields. The industry is generally heavily regulatedoften with price controls and is frequently government-owned and operated. Electricity is a natural phenomenon that occurs throughout nature and takes many different forms.
