Overview

You typically use instances of NSUnitElectricPotentialDifference to represent specific quantities of electric potential difference using the NSMeasurement class.

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).

The NSUnitElectricPotentialDifference class defines its base unit as volts, and provides the following units, which are initialized using NSUnitConverterLinear converters with the specified coefficients:
