What is the unit of measurement for electrical resistance?

The unit of measurement for electrical resistance is the ohm. This unit defines how much resistance a material offers to the flow of electric current. Named after the German physicist Georg Simon Ohm, the ohm is a fundamental concept in electrical engineering and physics, allowing for the calculation of resistance in various electrical circuits.

In practical terms, when one volt of electrical potential difference causes a current of one ampere to flow through a resistance of one ohm, it helps establish a clear relationship between voltage, current, and resistance, corresponding to Ohm's Law (V = I × R). Understanding resistance in terms of ohms is crucial for analyzing electrical circuits, troubleshooting issues, and designing effective electronic systems.

Other units listed, such as amps, watts, and volts, serve different functions in the realm of electricity: amps measure current, watts measure power, and volts measure electrical potential difference. Each plays a role in understanding electrical systems, but ohms specifically relate to resistance.
