Problem

A set of experimental readings for a conductor at constant temperature is given below:

\begin{array}{cc}V\,(\text{V}) & 2.0 \quad 4.1 \quad 6.2 \quad 8.0\\ I\,(\text{A}) & 0.39 \quad 0.83 \quad 1.20 \quad 1.63\end{array}

Considering the small measurement errors in the data, which of the following is the best estimate of the conductor’s resistance? (a)

4\,\Omega

(b)

15\,\Omega

(c)

5\,\Omega

(d)

10\,\Omega
