Four factors that will influence the resistance of a conductor are the material used, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor. The material used will affect the number of free electrons in the conductor, which will influence the electrical resistance. The length of the conductor affects the number of collisions the electrons must overcome, which will also affect the electrical resistance. The cross-sectional area of the conductor affects the number of electrons that can move through the conductor at once, which can also influence the resistance. Finally, the temperature of the conductor affects the kinetic energy of the electrons, which can affect the electrical resistance.
