What unit of measurement shows resistance in electricity?

The unit of measurement that shows resistance in electricity is the OHM. Resistance is a key concept in electrical circuits, as it quantifies how much a material opposes the flow of electric current. The OHM is defined as the amount of resistance that allows one ampere of current to flow when one volt is applied. This relationship is outlined in Ohm's Law, which states that voltage (in volts) equals current (in amperes) multiplied by resistance (in ohms).

Understanding resistance is crucial in designing and analyzing electrical circuits, as it helps determine how much current will flow under specific voltage conditions. The other units mentioned have distinct roles: a Watt measures power, a Volt measures electric potential, and an Ampere measures the flow of electric current. Each unit is vital in the realm of electricity, but only the OHM specifically addresses resistance.
