Question

A thick wire has a _______ resistance than thin wire.

• A. More
• B. Less
• C. Equal
• D. $A$ and $B$

Answer 1

The correct option is B Less

For same volume of the material of wire a thick wire will have more area of cross-section and lesser length as compared to thin wire of same material and same volume which will have more length and lesser area of cross-section.

As Resistance $R\propto l$ and $R\propto \frac{1}{A}$

Hence, thick wire will have less resistance than thin wire.
