Resistance is measured in which unit?

Explanation:
Resistance is measured in ohms (Ω). The ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces a current of one ampere; in other words, one ohm equals one volt per ampere. This ties directly to Ohm’s law, V = I × R, so resistance can be found by dividing voltage by current. For example, 6 volts with 2 amperes gives 3 Ω. The other units shown—volts, amperes, and watts—measure voltage, current, and power, not resistance.
