⚝ Given:-
⚝ To Find:-
⚝ Solution:-
Here, we have Length of a copper wire is 1m, Cross sectional area is 0.001 m² and The resistivity of copper is 1.6 × 10⁻⁸Ωm.
So,
To find out the resistance of the wire we will use the formula.
Where,
____________
♡ On applying the formula ♡
[tex]\qquad\tt{:\implies\:Resistance\:(\:R\:) =\: Resistivity\:(\:ρ\:) \times\: \dfrac{Length\: of\: a\: copper\: wire\:(\:l\:)}{Cross\: sectional\: area\:(\:A\:)}}[/tex]
[tex]\qquad\tt{:\implies\:Resistance\:(\:R\:) =\:1.6\:\times\:10^{-8}\:\times\: \dfrac{1}{0.001}}[/tex]
[tex]\qquad\tt{:\implies\:Resistance\:(\:R\:) =\:1.6\:\times\:10^{-5}\:Ω\:}[/tex]
[tex]\underline{\bf{\therefore\:Thus\:the\:resistance\:of\:the\:wire\:is\:1.6\:\times\:10\:^{-5\:}\:Ω\:\:\:.}}[/tex]
