Circuits: Resistance and Resistivity of a Wire

This lesson will study the resistance of a wire, two wires with the same cross sectional area and connected to the same voltage battery, the only difference being the length. This lesson will give a step... This lesson will study the resistance of a wire, two wires with the same cross sectional area and connected to the same voltage battery, the only difference being the length. This lesson will give a step by step in-depth explanation of the concept by looking at graphs and diagrams to derive formulas to solve.
