What unit is used to measure electrical resistance?

Electrical resistance is measured in Ohms, a unit named after the German physicist Georg Simon Ohm. In an electrical circuit, resistance quantifies how much a material opposes the flow of electric current. The greater the resistance measured in Ohms, the more difficult it is for current to pass through the material. This foundational concept is essential for understanding how various components in circuits interact and how they can be used to control and manipulate electrical energy.

Other units listed relate to different electrical properties: Farads measure capacitance, which is the ability of a component to store an electrical charge; Henries measure inductance, indicating how components like coils oppose changes in current; and Volts measure electric potential or voltage, which reflects the potential energy per unit charge available to drive current through a resistance. Each of these units plays a distinct role in electrical engineering and circuit design, but for resistance specifically, Ohm is the correct and pertinent unit of measurement.
