What is the unit of measurement for resistance?

Resistance is measured in Ohms. This is a fundamental concept in electrical engineering, established by Ohm's Law, which relates voltage, current, and resistance. According to this law, resistance is defined as the ratio of voltage (measured in Volts) across a conductor to the current (measured in Amperes) flowing through it. This relationship illustrates how much a component in an electrical circuit opposes the flow of electric current.

The other units mentioned pertain to different electrical properties: Volts measure electric potential, Amperes measure electric current, and Watts measure power, which is the product of voltage and current. Understanding these distinctions helps clarify the role of Ohms as the unit specifically describing resistance in an electrical context.
