A particular wire has a diameter of 1.7 mm and length of 1.3 m. If 45 μV is the potential drop measured across the wire when 3.0 mA flow in it, what is the resistivity of the metal from which it is made?

This is a very simple question. First find the resistance of the wire with V=IR
(you are given the current and the potential difference) And apply that to the formula given by the person above. The other values are given to you.
