| resistivity | It's the resistance of a sample multiplied by the ratio of it's cross sectional area to its length |
| Resistance | For circuit elements, it's an intrinsic value for the extent to which a particular material impedes the flow of electric charge |
| current | The electric current in a medium equals the electric charge transferred through a surface over a time interval |
| Ohm's law | The potential difference across two points in a conductor equals the current in the conductor multiplied by the electrical resistance of the conductor |
