WebbAfter all, if resistance occurs as the result of collisions between charge carriers and the atoms of the wire, then there is likely to be more collisions in a longer wire. More collisions mean more resistance. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. high school graduation dresses momWebbGiven two wires of the same length, the thicker wire would have smaller resistance than the thinner wire.
