## Ohm Definition and Usage

The ohm is the resistance between two points of an electrical conductor transmitting a current of one ampere when the potential difference is one volt.

The ohm is the SI derived unit for electrical resistance in the metric system. Ohms can be abbreviated as *Ω*, for example 1 ohm can be written as 1 Ω.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the resistance in ohms as an expression using current and voltage.

R_{Ω} = V_{V}I_{A}

The resistance in ohms is equal to the potential difference in volts divided by the current in amperes.

### Background and Origin

The ohm is named for the German physicist Georg Simon Ohm, who discovered Ohm’s Law. The ohm has been in use since the late 1800’s, although it’s been redefined several times.
