Electronics; Alternating Current;
A current which follows the pattern of a Sine wave. The voltage increases, reaches a peak, dips, goes into the negative, reaches a trough, curves up again back through 0 Volts into positive.

A.C. is used as a mains voltage supply because it can be efficiently stepped up and down from the power plant and can be transported through relatively small cables across the country due to the current being stepped down and the voltage increased to around 270kV so you get the same power, but you dont need huge cables. See also D.C.

1) "The mains supply in Britain is 240V A.C."

Also known as market anarchy or voluntarism/voluntaryism.

It's the idea that only voluntary cooperation (trade, the market) are legitimate forms of human interaction.

An anarcho-capitalist therefore envisions arbitration, security and defense to be solved through competing market agents instead of forceful territorial monopolists (as all statists including minarchists defend).

Alternating Current

This type of electrical current is called alternating because it switches direction. Direct current (DC) is often seen as the opposite of AC since DC only flows in one direction. Alternating current is used in most applications including the electricity that comes out of the outlet in your wall.
The AC flowing through this wire will kill you.
