Sep 12, 2022 · The 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 .
RESISTANCE meaning: 1 : refusal to accept something new or different often + from often + to; 2 : effort made to stop or to fight against someone or something
A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms. Good conductors, such as copper, have low resistance. Good insulators, such as rubber, have high resistance.

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.
Opposition of some force, thing, etc. to another or others. A force that retards, hinders, or opposes motion. Power or capacity to resist; specif., the ability of an organism to ward off disease. A process in which the ego opposes the conscious recall of anxiety-producing experiences.
The resistance is a measure of how difficult it is to pass current through a wire or component. Resistance depends on the resistivity. The 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.
