The resistivity of a wire is given by R=pL/A. Where p is the resistivity of the material, L is the length of the wire and A is the cross-sectional area of the wire.
a) If the diameter of the wire is .35mm calculate the cross-sectional area of the wire.
b) If the resistivity of the material is 3.56 x 10^-8 Ohm m and the length is 16m, calculate the resistance of the conductor.
