1 ohm is the unit of electrical resistance. It represents the amount of resistance that will allow 1 ampere (A) of current to flow when a potential difference (voltage) of 1 volt (V) is applied across a conductor.
In simple terms:
- 1 ohm = 1 volt / 1 ampere
It is the standard unit used to measure how much a material resists the flow of electric current. The lower the resistance (measured in ohms), the easier it is for current to flow.
