Ohms are a measurement of ______.

Ohms are a measurement of resistance in an electrical circuit. The concept of resistance refers to the opposition to the flow of electric current. When current flows through a conductor, resistance determines how much of that current can pass through for a given voltage. The relationship between voltage, current, and resistance is described by Ohm's Law, which states that voltage equals current times resistance (V = I × R). Therefore, the unit of resistance, the ohm, is crucial for understanding how electrical circuits behave under various conditions. In essence, calculating resistance is essential for designing safe and effective electrical systems, as it helps predict how changes in voltage will affect current flow.
