Resistance is the measurable opposition to the flow of electric current presented by a specific, complete object, such as a wire or a resistor.

It is an extrinsic property, meaning its value is not fixed but is instead dictated by the physical geometry of the object.

A long and narrow component will exhibit high resistance, making it difficult for current to pass through, whereas a short and wide component made of the same material will demonstrate low resistance, allowing current to flow more easily.

This characteristic makes resistance a practical parameter for circuit design, as it describes the real-world behavior of a fabricated part within an electrical system.

Resistivity, on the other hand, is a fundamental, intrinsic property of a material itself, completely independent of its shape or size.

It defines the inherent ability of a substance to conduct electric current, serving as a definitive metric for categorizing materials as conductors, semiconductors, or insulators.

A material with low resistivity, like copper, readily permits the flow of electrons, while a material with high resistivity, like glass, strongly inhibits it.

This value is determined by the material’s atomic structure and electronic band gaps, making it a essential constant for material scientists and engineers when selecting the base substance for a component, before any geometric considerations are applied.
