Definition of Current
In a solid metal conductor, current is the flow of free electrons (negatively charged), which move from negative to positive, creating an overall movement of charge in this direction. In molten or dissolved electrolytes, it is the flow of negative ions (anions) toward the positive terminal and vice versa. For more about this see electrolysis in the chemistry section
There are two types of current.
- 1An alternating current constantly changes direction. This is the kind of current used for most domestic electricity.Alternating current (AC).Advertisement
- 2A direct current passes in the same direction constantly. This is used to power electrified railway lines such as the London Underground.Direct current (DC).
