Resistivity

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).
