What is the unit of measurement for electrical resistance?

The unit of measurement for electrical resistance is ohms. This unit, named after the German physicist Georg Simon Ohm, quantifies how much a material opposes the flow of electric current. In an electrical circuit, resistance determines how much current will flow for a given voltage according to Ohm's Law, which states that voltage equals current times resistance (V = I × R).

Understanding resistance is crucial for anyone working with electrical systems, as it directly affects how electricity travels through different materials or components. While volts measure electrical potential, amperes (or amps) measure the flow of electric current, and watts measure power (the rate of energy transfer). Therefore, recognizing ohms as the standard unit of electrical resistance is essential in electrical engineering and related fields.
