What is the unit of measure for electrical resistance?

The unit of measure for electrical resistance is measured in ohms. The concept of resistance in electrical circuits refers to the opposition that a material presents to the flow of electric current. In ohms, indicated by the symbol Ω, this measurement helps quantify how much a component or material resists the passage of electric current.

For clarity, volts measure electrical potential or voltage, watts refer to power, representing the rate at which energy is consumed or generated, and amperes, also known as amps, measure electric current, or the flow of electric charge. Each of these units serves a distinct purpose in understanding electrical systems, but ohms specifically relate to the property of resistance, making it the correct answer in this context.
