esistance depends on the size and shape of a conductor. We expect a long wire to have higher resistance than a short one (everything else being the same) and a thicker wire to have a lower resistance than a thin one.  Resistance also depends on the intrinsic property of the conductor called the resistivity.  If the resistivity of a particular wire is 12.08x10-8 Ω⋅mΩ⋅m, the wire is 14.22mm in length, and the radius of the diameter of the wire is 1.33m, what is the resistance of the wire in units of Ohms (ΩΩ)?

Resistivity

Resistivity is a characteristic property of the conductor’s material that measures the extent to which the material opposes the flow of current. It is denoted by the Greek letter “rho”. Electrical resistivity, also known as specific resistance, depends on the nature of the material of the conductor and is unaffected by its dimensions.
