On what factors does the resistance of a conductor depend?
✓
Answer
The resistance $R$ of a conductor depends on : (1) its length $l$ as $R \propto l$ (2) its area of crosssection (i.e.. thickness of the conductor) as $R \propto \frac{1}{A}$ (3) the nature of the material of the conductor (i.e., resistivity of material of the conductor) (4) its temperature
