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?
