the strength of an electrical current measured in amperes
capacitance, capacity, electrical capacity
an electrical phenomenon whereby an electric charge is stored
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
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
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
opposition to the flow of electric current resulting from inductance and capacitance (rather than resistance)
(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
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
generation of an electromotive force (EMF) in a circuit by changing the current in that circuit; usually measured in henries
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
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
Type of:
physical phenomenon
a natural phenomenon involving the physical properties of matter and energy
