What is the unit of the electrical resistance?

Explanation:
Resistance is measured in ohms, symbol Ω. Ohm’s Law relates resistance to voltage and current as R = V / I, so one ohm is the amount of resistance that causes one ampere of current to flow when one volt of potential difference is applied. In other words, volts per ampere equals one ohm. The other units measure different quantities: voltage in volts, current in amperes, and power in watts. So the unit for resistance is the ohm.
