#potential_unit__potentialunit  a measure of the potential energy of a unit charge at a give point in a circuit relative to a reference point (ground)
  supertype:  electromagnetic_unit__electromagneticunit__emu  any of various systems of units for measuring electricity and magnetism
  subtype:  abvolt  a unit of potential equal to one-hundred-millionth of a volt
  subtype:  millivolt__mV__mv  a unit of potential equal to one thousandth of a volt
  subtype:  volt__V  a unit of potential equal to the potential difference between two points on a conductor carrying a current of 1 ampere when the power dissipated between the two points is 1 watt; equivalent to the potential difference across a resistance of 1 ohm when 1 ampere of current flows through it
  subtype:  kilovolt__kV__kv  a unit of potential equal to a thousand volts
