Rezistivaj

Rezistivaj is a term that can refer to several distinct concepts, primarily in the context of technology and materials science. The most common usage pertains to electrical resistance. Electrical resistivity, often denoted by the Greek letter rho (ρ), is an intrinsic property of a material that quantifies how strongly it resists the flow of electric current. It is the inverse of electrical conductivity. Materials with low resistivity, such as copper and silver, are considered good conductors and are used in electrical wiring. Conversely, materials with high resistivity, like rubber or glass, are insulators and are used to prevent the flow of electricity.

The unit of electrical resistivity in the International System of Units (SI) is the ohm-meter (Ω⋅m). Resistivity is temperature-dependent; for most conductors, it increases with temperature, while for semiconductors and insulators, it can decrease with increasing temperature. Understanding resistivity is crucial in the design of electronic components, wiring systems, and various other electrical applications.

Beyond electrical resistance, "rezistivaj" might occasionally appear in discussions related to other forms of resistance, such as thermal resistivity, which measures a material's opposition to heat flow. However, without further context, the electrical definition is the most prevalent interpretation of the term.
