What Is A 12 Volt DC Battery？ DC refers to direct current, which means the electric current always flows from the positive terminal to the negative terminal of the battery in one direction. A 12 Volt DC battery indicates a battery that provides direct current power at a voltage level of 12V. Conclusion
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons. When a battery is connected to an external electric load ...
