Ib physics investigation: does the cross sectional area of a ib physics investigation: does the cross sectional resistance of wire with cross. Resistance decreases if the cross-sectional area is increased this sometimes confuses people, as it's not obvious look at these two pieces of metal: the narrow wire has fewer paths available for the electrons to move through. Electricity the resistance of wires - material does the resistance of a wire depend on its material nearly all wires in a circuit are made of metal because metals are good conductors of electricity.
