electric current, any type of movement of electrical charge carriers, such together subatomic charged particles (e.g., electron having negative charge, protons having actually positive charge), ion (atoms that have actually lost or obtained one or much more electrons), or holes (electron deficiencies that might be assumed of as confident particles).

Electric current in a wire, where the fee carriers space electrons, is a measure up of the quantity of fee passing any suggest of the wire per unit that time. In alternate current the motion of the electrical charges is regular reversed; in direct existing it is not. In numerous contexts the direction of the current in electric circuits is taken as the direction of optimistic charge flow, the direction opposite come the actual electron drift. As soon as so characterized the existing is called conventional current.

Current is generally denoted by the price I. Ohm’s law relates the current flowing v a conductor come the voltage V and also resistance R; the is, V = IR. An alternative statement that Ohm’s law is I = V/R.

Current in gases and liquids generally consists of a flow of hopeful ions in one direction along with a flow of negative ions in opposing direction. To treat the all at once effect of the current, that direction is usually required to be the of the confident charge carrier. A present of negative charge relocating in the opposite direction is identical to a positive charge of the very same magnitude moving in the conventional direction and also must be contained as a contribution to the total current. Existing in semiconductors consists of the activity of holes in the conventional direction and electrons in the contrary direction.

Currents of countless other kinds exist, such together beams that protons, positrons, or fee pions and also muons in bit accelerators.

Electric current generates an accompanying magnetic field, together in electromagnets. As soon as an electric current flows in an outside magnetic field, it experience a magnetic force, together in electric motors. The heat loss, or energy dissipated, by electric existing in a conductor is proportional come the square of the current.

A common unit of electric existing is the ampere, i beg your pardon is characterized as a flow of one coulomb of charge per second, or 6.2 × 1018 electrons per second. The centimetre–gram–second devices of present is the electrostatic unit of fee (esu) per second. One ampere equates to 3 × 109 esu every second.

Commercial power lines do available about 100 amps to a typical home; a 60-watt lightbulb pulls about 0.5 amp that current and a one-room air conditioner around 15 amps. (For more on electric current, see electricity: straight electric current and electricity: alternative electric currents.)
