The resistance of a conductor is inversely proportional to the cross sectional area of the conductor.
Explanation:
The resistors are used to resist or block the flow of current in any circuit. As per Ohm's law, resistance is inversely proportional to the current flow or charge in the circuit. But the resistance of a conductor will depend on the length of the conductor and cross sectional area of the conductor along with specific resistance of the material with which the conductor is made.
[tex]R = \frac{Rho* L}{A}[/tex]
Here, Rho is the specific resistance, L is the length of the conductor and A is the cross sectional area of the conductor.
As the resistance offered by the conductor will be directly proportional to the length of the conductor and inversely proportional to the cross sectional area of the conductor. So the resistance of a conductor is inversely proportional to the cross sectional area of the conductor.
