The difference in electric potential between two points is called voltage. It's measured in volts (V), equivalent to joules per coulomb (J/C). When comparing two points, the point with the higher electric potential is labelled positive (+), and the point with the lower electric potential is negative (-). If two points are at the same electric potential, the voltage between them is zero.
