Question

 What happens to the resistance as the conductor is made thinner?

Advertisements

Solution

The resistance of a wire can be represented by the following equation: 

`R=(rhol)/A`

So, when the conductor is made thinner, its area of cross-section will decrease, since resistance is inversely proportional to the area of the conductor. Therefore, its resistance will increase.
