• electrophori
  plural

1. An electrostatic generator, constructed like one half of a large capacitor, the other half being any grounded surface, such as a table. A small charge is given to the electrophorus when it is near the grounded surface, effectively charging it like capacitor. As the electrophorous is lifted away from the surface, its voltage relative to the surface increases (as the capacitance decreases).
