| − | U is the potential difference measured across the resistance in units of volts (V); |
||
| − | I is the current through the resistance in units of amperes (A); |

| − | R is the resistance of the conductor in units of ohms (Ω); |
||
| − | |||
| − | Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them. |
