Question

The resistance of a conductor is directly proportional to?

Answer 1

1. Resistance of a conductor is a property by virtue of which it opposes the flow of electric current in it.
2. Resistance of a conductor, $R$ is given by $R=\frac{\rho l}{A}$,where $\rho$is the resistivity of the conductor, $l$ is the length of the conductor, and $A$is the area of the cross-section of the conductor.
3. As we can see from the expression, the resistance of a conductor is in direct proportion with the resistivity and the length of the conductor.
