electric current \
electric current \,
electrical current \
electrical current \,
the movement of electrically charged particles ,
atoms ,
or ions ,
through solids ,
liquids ,
gases ,
or free space ;
the term is usually used of relatively smooth movements of electric charge through conductors ,
whether constant or variable .
Sudden movements of charge are usually referred to by other terms ,
such as {
spark }
or {
lightning }
or {
discharge }.
In metallic conductors the electric current is usually due to movement of electrons through the metal .
The current is measured as the rate of movement of charge per unit time ,
and is counted in units of amperes .
As a formal definition ,
the direction of movement of electric current is considered as the same as the direction of movement of positive charge ,
or in a direction opposite to the movement of negative charge .
Electric current may move constantly in a single direction ,
called {
direct current } (
abbreviated {
DC }),
or may move alternately in one direction and then the opposite direction ,
called {
alternating current } (
abbreviated {
AC }).
