What happens to the resistance of a conductor as the length of the material increases?

The resistance of a conductor is directly related to its length. When the length of the conductor increases, the electrons that flow through it encounter more obstacles or collisions with atoms within the material. This phenomenon is described by the formula for resistance:

[ R = \rho \frac{L}{A} ]

where ( R ) is resistance, ( \rho ) is resistivity (a material property), ( L ) is the length of the conductor, and ( A ) is the cross-sectional area. As the length ( L ) increases while keeping the material and cross-sectional area constant, the overall resistance ( R ) will increase because there are more obstacles for the current to navigate. Therefore, it is clear that as the length of the conductor rises, the resistance also rises, making the correct answer the one that states that the resistance increases.
