WebWhere: R is the resistance in ohms (Ω), L is the length in metres (m), A is the area in square metres (m 2), and where the proportional constant ρ (the Greek letter “rho”) is known as Resistivity.. Electrical Resistivity. The electrical resistivity of a particular conductor material is a measure of how strongly the material opposes the flow of electric current through it. WebImpedance is measured in ohms (Ω) just like electrical resistance and can even be thought of as a type of “AC resistance” in an AC circuit. Technically speaking, impedance is the combination of DC resistance and any reactance in an AC circuit. Resistance is defined simply as the opposition to the flow of electric current.
