Unit dV
Name decivolt
Category Electric Potential
Details A decivolt (dV) is a unit of electric potential, which represents the voltage difference between two points in an electrical circuit. It is equal to one-tenth (0.1) of a volt (V). The term "decivolt" is derived from "deci-", which means tenth, and "volt," after the scientist Alessandro Volta, who made significant contributions to the field of electricity and invented the voltaic pile, an early form of the battery.

Electric potential, commonly known as voltage, refers to the potential energy that a charged particle has because of its position in an electric field. It indicates the force that drives electric charges to flow in a circuit and create an electric current. It's typically measured in volts (V), but other subunits like the decivolt (dV) can be used for smaller potential differences.
