elastance, electrical elastance
the reciprocal of capacitance
-
charge, electric charge
the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons
-
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
-
dielectric heating
heating of an insulator by a high-frequency electric field
-
inductance, 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, potential difference, potential drop, voltage
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, resistance, resistivity
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)
-
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
-
electrostatic charge
the electric charge at rest on the surface of an insulated body (which establishes and adjacent electrostatic field)
-
positive charge
having a deficiency of electrons; having a higher electric potential
-
negative charge
having a surplus of electrons; having a lower electric potential
-
mutual induction
generation of electromotive forces in each other by two adjacent circuits
-
self-induction
generation of an electromotive force (EMF) in a circuit by changing the current in that circuit; usually measured in henries
-
juice
electric current
-
evoked potential
the electrical response of the central nervous system produced by an external stimulus
-
resting potential
the potential difference between the two sides of the membrane of a nerve cell when the cell is not conducting an impulse
-
ohmage
the ohmic resistance of a conductor
-
amplitude distortion, nonlinear distortion
distortion that occurs when the output signal does not have a linear relation to the input signal
-
thermionic current
an electric current produced between two electrodes as a result of electrons emitted by thermionic emission
