Table of Electrical Resistivity and Conductivity

Cross-Sectional Area: If the cross-section of a material is large, it can allow more current to pass through it. Similarly, a thin cross-section restricts current flow. Length of the Conductor: A short conductor allows current to flow at a higher rate than a long conductor. It's a bit like trying to move a lot of people through a hallway.
