transposition - (electricity) a rearrangement of the relative positions of power lines in order to minimize the effects of mutual capacitance and inductance; "he wrote a textbook on the electrical effects of transposition"

amplification - (electronics) the act of increasing voltage or power or current

outlet box - (electricity) receptacle consisting of the metal box designed for connections to a wiring system

physical phenomenon - a natural phenomenon involving the physics of matter and energy

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)

direct - of a current flowing in one direction only; not alternating; "direct current"

alternating - of a current that reverses direction at regular intervals; "alternating current"

high-tension - subjected to or capable of operating under relatively high voltage; "high-tension wire"

low-tension, low-voltage - subjected to or capable of operating under relative low voltage

inductive - arising from inductance; "inductive reactance"

galvanic, voltaic - pertaining to or producing electric current by chemical action; "a galvanic cell"; "a voltaic (or galvanic) couple"

multiphase, polyphase - of an electrical system that uses or generates two or more alternating voltages of the same frequency but differing in phase angle

alternating current, AC - an electric current that reverses direction sinusoidally; "In the US most household current is AC at 60 cycles per second"

direct current, DC - 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

energy - (physics) the capacity of a physical system to do work; the units of energy are joules or ergs; "energy can take a wide variety of forms"

stir - emotional agitation and excitement
