The ohm (symbol: Ω) is the SI unit of electrical resistance. It measures how much a material opposes the flow of electric current. One ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt produces a current of one ampere. Essentially, it's a measure of how difficult it is for electric current to pass through a conductor.

In the International System of Units (SI), the ohm (symbol: Ω) is the unit of electrical resistance. It is defined as the resistance between two points of a conductor when a constant potential difference of one volt (1 V) applied between those points produces a current of one ampere (1 A). Therefore, one ohm is equivalent to one volt per ampere (1 Ω = 1 V/A).
