You typically use instances of
NSUnit to represent specific quantities of electric potential difference using the
Electric Potential Difference
Electric potential difference is the amount of electric potential energy of a point charge at a point in space. The SI unit for electric potential difference is the volt (V), which is derived as the difference in electric potential energy between two points of a linear conductor when an electric current of one ampere dissipates one watt of power between those points (1V = 1W/1A).
