Electrical resistivity is a property of materials and is different from electrical resistance which is a property of a component. Resistivity is also known as Specific Electrical Resistance or Volume Resistivity. Resistivity can also be defined as the inverse of the conductivity of a material - Ï = 1 / Ï.It is a measure of how a material opposes the flow of electric current. The SI unit of resistivity is ohm meter (Ï.m).
Resistance is calculated by (resistivity)*(length)/(cross sectional area). First consider a wire conductor. Electrical resistivity is a property of the substance (it usually will vary with temperature). The thicker a wire is (larger cross sectional area) will lower the resistance.
