In the International System of Units (SI), **ohm** (symbol: Ω) is the unit of electrical resistance.
It is defined as the amount of resistance in a conductor when a voltage of one volt (V) causes a current of one ampere (A) to flow through it.
Mathematically, it is expressed as:
\[
1 \, \text{ohm} = \frac{1 \, \text{volt}}{1 \, \text{ampere}}
\]
This means that if the resistance is 1 ohm, a 1-volt potential difference across the conductor will create a current of 1 ampere.
