• conductance

Answer 1

The graph of V (on y-axis) and I (on x-axis) is found to be a straight line. The slope of the straight line gives resistance.

Explanation:

According to Ohm’s law, \(V=IR\). Therefore, the slope of a V–I graph represents the resistance of the conductor.

\[ {\text{Slope}=\frac{V}{I}=R} \]
