electricity

1. A physical phenomenon associated with stationary or moving electrons and protons (synset 111470244)
   associated with:

   • transposition - (electricity) a rearrangement of the relative positions of power lines in order to minimize the effects of mutual capacitance and inductance
   • amplification - (electronics) the act of increasing voltage or power or current
   • earth, ground - a connection between an electrical device and a large conducting body, such as the earth (which is taken to be at zero voltage)
   • outlet box - (electricity) receptacle consisting of the metal box designed for connections to a wiring system
   • hot, live - charged or energized with electricity
   • direct - (of a current) flowing in one direction only
   • alternating - (of a current) reversing direction
   • high-tension - subjected to or capable of operating under relatively high voltage
   • low-tension, low-voltage - subjected to or capable of operating under relative low voltage
   • inductive - arising from inductance
   • galvanic, voltaic - pertaining to or producing electric current by chemical action
   • multiphase, polyphase - of an electrical system that uses or generates two or more alternating voltages of the same frequency but differing in phase angle
   is a type of: physical phenomenon - a natural phenomenon involving the physical properties of matter and energy
   subtypes:

   • galvanism - electricity produced by chemical action
   • hydroelectricity - electricity produced by water power
   • photoelectricity - electricity generated by light or affected by light
   • piezo effect, piezoelectric effect, piezoelectricity - electricity produced by mechanical pressure on certain crystals (notably quartz or Rochelle salt); alternatively, electrostatic stress produces a change in the linear dimensions of the crystal
   • static electricity - electricity produced by friction
   • current electricity, dynamic electricity - a flow of electric charge
   • thermoelectricity - electricity produced by heat (as in a thermocouple)
2. Energy made available by the flow of electric charge through a conductor (synset 111470903)
   "they built a car that runs on electricity"; "The power went oout around midnight"
   is a type of: energy, free energy - (physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs
   subtypes:

   • ac, alternating current, alternating electric current - an electric current that reverses direction sinusoidally
   • dc, direct current, direct electric current - an electric current that flows in one direction steadily
   • signal - an electric quantity (voltage or current or field strength) whose modulation represents coded information about the source from which it comes
   same as: electrical energy, power
3. Keen and shared excitement (synset 107529839)
   "the stage crackled with electricity whenever she was on it"
   is a type of: stir - emotional agitation and excitement
