I. (noun)
Sense 1
Meaning:
A physical phenomenon involving electricity
Classified under:
Nouns denoting natural phenomena
Hypernyms ("electrical phenomenon" is a kind of...):
physical phenomenon (a natural phenomenon involving the physical properties of matter and energy)
Hyponyms (each of the following is a kind of "electrical phenomenon"):
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)
electrical disturbance (electrical signals produced by unwanted sources (atmospherics or receiver noise or unwanted transmitters))
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))
skin effect (the tendency of high-frequency alternating current to distribute near the surface of a conductor)
reluctance ((physics) opposition to magnetic flux (analogous to electric resistance))
reactance (opposition to the flow of electric current resulting from inductance and capacitance (rather than resistance))
electric resistance; electrical resistance; impedance; ohmic resistance; resistance; resistivity (a material's opposition to the flow of electric current; measured in ohms)
conductance (a material's capacity to conduct electricity; measured as the reciprocal of electrical resistance)
electric potential; potential; potential difference; potential drop; voltage (the difference in electrical charge between two points in a circuit expressed in volts)
inductance; induction (an electrical phenomenon whereby an electromotive force (EMF) is generated in a closed circuit by a change in the flow of current)
dielectric heating (heating of an insulator by a high-frequency electric field)
current; electric current (a flow of electricity through a conductor)
pyroelectricity (generation of an electric charge on certain crystals (such as tourmaline) as a result of a change in temperature)
charge; electric charge (the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons)
elastance; electrical elastance (the reciprocal of capacitance)
capacitance; capacity; electrical capacity (an electrical phenomenon whereby an electric charge is stored)
amperage (the strength of an electrical current measured in amperes)
