Resistivity – מילון אנגלי-אנגלי
resistivity
n.
ability to resist; resistance, quality of a conductor which resists an electrical current (Electricity)
Electrical resistivity and conductivity
Electrical resistivity (also known as
resistivity,
specific electrical resistance, or
volume resistivity) is an intrinsic property that quantifies how strongly a given material opposes the flow of
electric current. A low resistivity indicates a material that readily allows the flow of
electric current. Resistivity is commonly represented by the
Greek letter ρ (
rho). The
SI unit of electrical resistivity is the
ohm⋅
metre (Ω⋅m) although other units like
ohm⋅
centimetre (Ω⋅cm) are also in use. As an example, if a solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m.
resistivity
Noun
1. a material's opposition to the flow of electric current; measured in ohms
(synonym) electric resistance, electrical resistance, impedance, resistance, ohmic resistance
(hypernym) electrical phenomenon
(hyponym) ohmage
Resistivity
an intrinsic property of a material determining the materials resistance to the flow of current. Resistance in ohms is equal to the resistivity of the material multiplied by the cross sectional area of the material divided by the length of the material. Resistivity is frequently used to specify electrically active doping level and also as a measure of the ionic content of water.
