Alternating Current versus Direct Current | Physics
Direct current (DC) is the flow of electric current in only one direction. It refers to systems where the source voltage is constant. The voltage source of an alternating current (AC) system puts out [latex]V={V}_{0}text{sin 2}pi {ft}[/latex], where V is the voltage at time t, V 0 is the peak voltage, and f is the frequency in hertz.
What Current Does a Battery Produce? (AC Or DC Current)
Batteries produce DC because the chemical reaction that generates electricity inside the battery only flows in one direction. This unidirectional flow of electrons creates a DC circuit. The terminals of a battery are always labeled with "+" and "-" symbols to indicate the polarity of the voltage.
The battery voltage is about 3.7 V. Lithium batteries are popular because they can provide a large amount current, are lighter than comparable batteries of other types, produce a nearly constant voltage as they discharge, and only slowly lose their charge when

Batteries put out direct current, as opposed to alternating current, which is what comes out of a wall socket. With direct current, the charge flows only in one direction. With alternating current, the charges slosh back and forth, continually reversing direction.
