voltage
     n 1: the rate at which energy is drawn from a source that
          produces a flow of electricity in a circuit; expressed
          in volts syn: electromotive force, emf
     2: the difference in electrical charge between two points in a
        circuit expressed in volts syn: electric potential, potential,
         potential difference, potential drop

voltage
     
         or "potential difference", "electro-motive
        force" emf a quantity measured as a signed difference
        between two points in an electrical circuit which, when
        divided by the resistance in ohms between those points,
        gives the current flowing between those points in amperes,
        according to ohm's law.  voltage is expressed as a signed
        number of volts v.  the voltage gradient in volts per metre
        is proportional to the force on a charge.
     
        voltages are often given relative to "earth" or "ground" which
        is taken to be at zero volts.  a circuit's earth may or may
        not be electrically connected to the actual earth.
     
        the voltage between two points is also given by the charge
        present between those points in coulombs divided by the
        capacitance in farads.  the capacitance in turn depends on
        the dielectric constant of the insulators present.
     
        yet another law gives the voltage across a piece of circuit as
        its inductance in henries multiplied by the rate of change
        of current flow through it in amperes per second.
     
        a simple analogy likens voltage to the pressure of water in a
        pipe.  current is likened to the amount of water charge
        flowing per unit time.
