Problem

In an experiment, current measured is,

I = 10.0 \text{ A}

, potential difference measured is

V = 100.0 \text{ V}

, length of the wire is

31.4 \text{ cm}

and the diameter of the wire is

2.00 \text{ mm}

(all in correct significant figures). Find resistivity of the wire in correct significant figures. [Take

\pi = 3.14

, exact]
