  subtype:  electrical_elastance__elastance  the reciprocal of capacitance
  subtype:  electric_charge__charge  the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons; "the battery needed a fresh charge"
     subtype:  electrostatic_charge__electrostaticcharge  the electric charge at rest on the surface of an insulated body (which establishes and adjacent electrostatic field)

     subtype:  thermionic_current  an electric current produced between two electrodes as a result of electrons emitted by thermionic emission
  subtype:  dielectric_heating  heating of an insulator by a high-frequency electric field
  subtype:  induction.electrical_phenomenon  an electrical phenomenon whereby an electromotive force (EMF) is generated in a closed circuit by a change in the flow of current
     subtype:  electromagnetic_mutual_induction__mutual_induction  generation of electromotive forces in each other by two adjacent circuits
     subtype:  self-induction  generation of an electromotive force (EMF) in a circuit by changing the current in that circuit; usually measured in henries
  subtype:  electric_potential__potential__potential_difference__potentialdifference__potential_drop__potentialdrop__voltage  the difference in electrical charge between two points in a circuit expressed in volts

     subtype:  resting_potential__restingpotential  the potential difference between the two sides of the membrane of a nerve cell when the cell is not conducting an impulse
  subtype:  conductance  a material's capacity to conduct electricity; measured as the reciprocal of electrical resistance
  subtype:  electric_resistance__electrical_resistance__impedance__resistance__resistivity__ohmic_resistance__ohmicresistance  a material's opposition to the flow of electric current; measured in ohms
     subtype:  ohmage  the ohmic resistance of a conductor
  subtype:  reactance  opposition to the flow of electric current resulting from inductance and capacitance (rather than resistance)
