Resistivity and Conductivity
Completion requirements
Get a feeling for the interplay of resistivity and geometry in determining the resistance of a wire by manipulating the interactive simulation at the bottom of the page linked above.
Review the lecture on currents to see how resistance and resistivity are related. Then watch this video, which explains the difference between resistance, which is the ratio of voltage to current, resistor, a device that creates resistance, and resistivity, which is a material-dependent property of the device.
