The ohm is the unit of electrical resistance.

Explanation:
Resistance is measured in ohms. The ohm is defined as one volt per ampere, so if one volt is applied and one ampere flows, the resistance is one ohm. This ties directly to Ohm’s law, V = I R, which shows how voltage, current, and resistance relate. The other units measure different quantities: the watt is for power, the volt for electric potential difference, and the ampere for current.
