Resistivity
A measure of how strongly a given material opposes the flow of electric current.
Specific Resistance
Expressed in the format μΩm, it refers to the resistivity of a material, measured by the resistance of a one-metre cube.
Unit of Resistivity
Resistivity is expressed in microhms per metre (μΩm).
Copper Resistivity
The resistivity of copper is 0.0172 μΩm, indicating the resistance of a one-metre cube of copper.
Greek letter for Resistivity
The specific resistance or resistivity of a material is represented by the Greek letter rho (ρ).
Formula for Resistance calculation
The resistance of a conductor can be calculated using the formula R = ρ (P x L/A), where P is the resistivity.
Resistance unit
The resistance of a conductor material is normally very low and is expressed in microhms (μΩ).
