Bookmark or Share- 9.4: Resistivity and Resistance - Physics LibreTextsThe resistivity is a characteristic of the material used to fabricate a wire or other electrical component, whereas the resistance is a characteristic of the wire or component. To calculate the resistance, consider a section of conducting wire with cross-sectional area A, length L, and resistivity ρ ρ.
- 9.3 Resistivity and Resistance - University Physics Volume 2 - OpenStaxThe resistivity of a material is a measure of how strongly a material opposes the flow of electrical current. The symbol for resistivity is the lowercase Greek letter rho, ρ ρ, and resistivity is the reciprocal of electrical conductivity:
- RESISTANCE | English meaning - Cambridge Dictionarya force that acts to stop the progress of something or make it slower: The car's speed was reduced by air / wind resistance. [ C or U ] physics specialized. the degree to which a substance prevents the flow of an electric current through it: Copper has (a) low resistance. Fewer examples.
- Current, resistance, and resistivity review - Khan AcademyCurrent, resistance, and resistivity review. Review the key terms, equations, and skills related to current, resistance, and resistivity, including how to find the current direction and what resistance depends on.
- What is Resistance? | FlukeResistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
