What is the standard unit of measure for electrical resistance?

The standard unit of measure for electrical resistance is the Ohm. This unit is defined as the amount of resistance that allows one ampere of current to flow when one volt of electrical potential is applied. Ohm's Law, which states that voltage equals current times resistance (V = IR), provides the foundational relationship between these three electrical parameters. The significance of the Ohm in electrical engineering and instrumentation cannot be overstated, as it directly relates to how components in a circuit interact and the efficiency of those interactions.

Other units mentioned, such as the Volt, measure electrical potential; the Ampere measures electrical current, and the Watt measures electrical power. While these units are all integral to understanding electrical systems, they serve different purposes and are not interchangeable with the concept of resistance.
