What is the unit of resistance?

Explanation:
The unit of resistance is the ohm, symbol Ω. Resistance tells you how much a component resists current flow. By definition, one ohm equals one volt per ampere (Ω = V/A). So if 1 volt across a component causes 1 amp of current, that component has a resistance of 1 ohm. The other options measure different things: watts and kilowatts measure power, and amperes measure current.
