#### Question

What would be the effect on the resistance of a metal wire of:

increasing its diameter?

#### Solution

The resistance of a conductor is inversely proportional to its area of cross-section, i.e. *R* α 1 / *A*. So on increasing its diameter, its resistance will decrease.

Is there an error in this question or solution?
