What is the unit of resistance?

Explanation:
Resistance is how much a component slows down or limits electric current. The unit for this is the ohm (Ω). It’s defined so that one ohm is the resistance between two points of a conductor when a constant potential difference of one volt, applied to those points, produces a current of one ampere, with one watt of power being dissipated. Put simply, Ohm's law V = I × R means resistance equals voltage divided by current. So if you apply 1 volt and observe 1 ampere, the resistance is 1 ohm. The other terms are units for voltage (volts), current (amperes), and capacitance (farads).
