Question

State the relation between the resistance of a conductor resistivity of a conductor length l of a conductor and area of cross section of a conductor and resistivity

Answer 1

According to Eq. (131), the resistance of a wire is proportional to its length, and inversely proportional to its cross-sectional area. The constant of proportionality is called the resistivity of the material making up the wire. The units of resistivity are ohm-meters
