What happens to the resistance in a circuit if the length of the conductor increases?

The resistance in a circuit is directly related to the length of the conductor. As the length of the conductor increases, the resistance also increases. This relationship can be understood through the fundamental principles of electricity.

Resistance is determined by a number of factors, including the material of the conductor, its cross-sectional area, and its length. The longer the conductor, the more collisions the electrons traveling through it will encounter with the atoms in the material. These collisions impede the flow of electrons, effectively increasing the resistance.

This relationship is defined by the formula for resistance, which states that resistance is proportional to the length of the conductor, among other factors. Therefore, when the length increases, the resistance correspondingly increases, which aligns with the correct answer.
