If vacuum energy can be increased or decreased by changing the angular momentum of the spinning flux-current field by applying a voltage at right angles to that field then it will have nothing to do with electron particles which only tie the voltage reference point; but be a spinning volume of 3D power existing in unit time.  Thus [V*ICos Ø]dt or energy in Watt-seconds/cubic metre will define a unit of magnoflux vacuum energy.  As the spin increases per unit volume then the temperature goes up.

For a demonstration please take a look at this experiment
