In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). current (AC).
According to Wikipedia
http://en.wikipedia.org/wiki/Direct_current
A battery has two terminals- a positive and a negative.When a battery is in use, current flows from the positive terminal of the battery around the circuit back to the negative terminal in one direction.

Batteries are a source of direct current because they product power (voltage and current) in only one direction.
Alternating current. Direct current is used in batteries.
Simple source of direct current are Batteries.
Batteries store DC, or Direct Current. The correct term for AC is Alternating Current.
Direct current
direct current
Not directing current but DIRECT current, meaning there is no oscillation in the current.
DC (direct current, a current that flows in a single direction).
A Direct Current, DC.
Batteries and generators provide DC, Direct Current electricity.
These things use dc: batteries provide direct current, so anything run by batteries; electrolysis, used for electroplating, aluminium manufacture and the production of sodium hydroxide.
Batteries provide Direct Current (DC) while household outlets provide Alternating Current (AC).
