The reciprocal of conductivity
In general, the resistance to electric current of a material. In particular, the degree to which a material resists the flow of electricity or heat
A measure of the resistance to current flow in a material
In electricity, a characteristic proportionality factor equal to the resistance of a centimeter cube of a substance to the passage of an electric current perpendicular to two parallel faces Also called specific resistance R = ρ( l/A ) where R is the resistance of a uniform conductor, l is the length, A is its cross-sectional area, and ρ is its resistivity
The capacity for or tendency toward resistance The resistance per unit length of a substance with uniform cross-section Resistance is the opposition to electric current characteristic of a medium, substance, or circuit element
The characteristic of a material to impede the flow of electrons (electrical current) It is the material’s electrical resistance for a unit volume This value is specific to a material and not its geometry
The ability of an insulator to resist the flow of electric current through it It is expressed in ohm-cm
The electrical resistance of a formation
{i} ability to resist; resistance, quality of a conductor which resists an electrical current (Electricity)
Referring to the measurment of the resistance of a material to electric current either through its volume or on its surface The unit of volume resistivity is ohm-centimeter; the unit of surface resistivity is the ohm
Resistivity uses Greek letter Rho where Resistance = Rho * length / cross sectional area Rho (Ohm Metres) = Resistance of 1 metre length of material with 1 square metre cross section Rho (Ohm Metres) = Rho (Micro-Ohm metres) * 0 000001(E-6) Rho (Ohm Metres) = Rho (Ohm cm) * 0 01(E-2) Rho (Ohm Metres) = Rho (Micro-Ohm cm) * 0 00000001(E-8) The default value is that for pure copper at 20 degrees C is 1 68E-8 (0 0000000168) Ohm Metres
The ability of a material to resist passage of electrical current either through its bulk or on a surface The unit of volume resistivity is the ohm-cm, of surface resistivity, the ohm
The ability of a material to resist passage of electric current through itself or on its surface
The property of a material which resists the flow of electrical current Also called specific resistance The ratio of electric-field intensity to current density The reciprocal of resistivity is conductivity
– the resistance of a unit length of a conductor of unit cross sectional area (see Table 18 1)
A technique using electrodes in contact with the ground to measure electrical resistivity The depth of investigation is a function of the electrode spacing and geometry
r Resistivity of material defines cincentration of carriers in the bulk substrate Range: between 1 and tens of thousands Ohms-cm
The opposition of a medium which opposes or reduces current flow Any substance which reduces or eliminates current flow, reciprocal of conductivity
a material's opposition to the flow of electric current; measured in ohms
Electrical resistance of a conductor of unit cross-sectional area and unit length. The resistivity of a conductor depends on its composition and its temperature. As a characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric current. As temperature increases, the resistivity of a metallic conductor usually increases and that of a semiconductor usually decreases
A proportionality constant that relates the length and cross-sectional area of a given electric conductor to its resistance, at a given temperature
A proportionality factor characteristic of different substances equal to the resistance that a centimetre cube of the substance offers to the passage of electricity, the current being R = rL/A, where R is the resistance of a uniform conductor, L its length, A it cross-sectional area, and r its resistivity Resistivity is usually expressed in ohm-centimetres The ability of a material to resist passage of electrical current either through its bulk or on a surface
The degree to which a material opposes the flow of electricity or heat
The geometry independent parameter of a material that determines the relationship between the current through it and the current across it Resistance of a cylinder of material is: resistance = resistivity * (length / area)
– The ability of a material to resist passage of electrical current through its bulk or on a surface The unit of volume resistivity is the ohm-cm; of surface resistivity, the ohm
