Problem

In an experiment, the current measured is I=10.0 AI=10.0\ \text{A}, the potential difference measured is V=100.0 VV=100.0\ \text{V}, the length of the wire is 31.4 cm31.4\ \text{cm}, and the diameter of the wire is 2.00 mm2.00\ \text{mm}, all in correct significant figures. Find the resistivity of the wire in correct significant figures. Take π=3.14\pi=3.14 exactly.
