Which term is used to describe the measure of electrical resistance in a conductor?

The term that describes the measure of electrical resistance in a conductor is Ohm. This unit is specifically defined by one volt per ampere, indicating the opposition a material presents to the flow of electric current. The concept was formulated by Georg Simon Ohm and is fundamental in electrical engineering as it allows for the quantification of how much a material will resist electricity.

In the context of electrical components, this resistance affects how much current will flow through the conductor when a voltage is applied. Understanding resistance is crucial for designing circuits, ensuring safe and effective operation, and calculating how components will interact within an electrical system.

The other terms mentioned relate to different electrical properties: capacitance measures a component's ability to store an electric charge, inductance describes a component's ability to store energy in a magnetic field when an electric current passes through it, and impedance encompasses both resistance and reactance in an AC circuit. Thus, while they are important concepts in electrical theory, they do not pertain specifically to the measure of electrical resistance as Ohm does.
