Explanation:

•One volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.

-Unit of: Electric potential, electromotive force

-Unit system: SI derived unit

-In SI base units: kg·m2·s−3·A−1

•Rheostat, adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit. The rheostat can adjust generator characteristics, dim lights, and start or control the speed of motors.
