In an electrical circuit, resistance is the component's opposition to the electric flow.

Explanation:
Resistance is a property of a component that describes how strongly it opposes the flow of electric current. This opposition sets how much current flows for a given voltage, described by Ohm's law I = V/R. A higher resistance means less current, while a lower resistance means more current, assuming the voltage is fixed. This concept is different from a source of energy (which pushes charges around), a device for storing charge (like a capacitor), or a path for current (a conductor with low resistance). So, the best description is the opposition to current flow.
