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

amperage - the strength of a electrical current measured in amperes

capacitance, electrical capacity, capacity - an electrical phenomenon whereby an electric charge is stored

elastance, electrical elastance - the reciprocal of capacitance

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"

pyroelectricity - generation of an electric charge on certain crystals (such as tourmaline) as a result of a change in temperature

current, electric current - a flow of electricity through a conductor; "the current was measured in amperes"

dielectric heating - heating of an insulator by a high-frequency electric field

induction - an electrical phenomenon whereby an electromotive force (EMF) is generated in a closed circuit by a change in the flow of current

electric potential, potential difference, potential drop, voltage, potential - the difference in electrical charge between two points in a circuit expressed in volts

conductance - a material's capacity to conduct electricity; measured as the reciprocal of electrical resistance

electric resistance, electrical resistance, impedance, ohmic resistance, resistivity, resistance - a material's opposition to the flow of electric current; measured in ohms

reactance - opposition to the flow of electric current resulting from inductance and capacitance (rather than resistance)

reluctance - (physics) opposition to magnetic flux (analogous to electric resistance)

skin effect - the tendency of high-frequency alternating current to distribute near the surface of a conductor

distortion - a change (usually undesired) in the waveform of an acoustic or analog electrical signal; the difference between two measurements of a signal (as between the input and output signal); "heavy metal guitar players use vacuum tube amplifiers to produce extreme distortion"

electrical disturbance - electrical signals produced by unwanted sources (atmospherics or receiver noise or unwanted transmitters)

electromotive force, emf, voltage - the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts
