What kind of current does a dry cell battery produce?
The current derived from a dry cell battery, the mostly common used batteries today, is direct current, or DC, because the positive and negative terminals are fixed.Unidirectional FlowDirect current means that the electric current always flows in the same direction. Current from a battery is direct current because it is unidirectional.Direct Current CircuitA direct current circuit is necessary to keep an electric current flowing. Such a circuit typically consists of a battery and a source of conduction, like a wire, that runs from the positive end to the negatively charged terminal.Sources of Direct CurrentBatteries are among the best sources of direct current, but others include solar cells, fuel cells and certain types of electric generators.Dry Cell vs. Wet Cell BatteriesA dry cell’s electrolytes are contained in a low-moisture paste, while a wet cell battery’s electrolytes are contained in liquid.
