## Answers

The resistance of a conductor is inversely proportional to its area of cross section.A dummy approach: The concept of current flow in a conductor is analogous to liquid flow in a pipe.As the amount of current flowing at constant voltage increases with increase in cross sectional area, resistance decreases.13priya
