The resistivity of a given wire of cross sectional area 0.7mm is 4.9*10-4mm.Calculate the resistance of 2m length of the wire
Masja [62]

Answer: 1.4\ \Omega

Explanation:

Given

Cross-sectional area A=0.7\ mm^2

Resistivity \rho =4.94\times 10^{-4}\ \Omega-mm

Length of wire l=2\ m\ or\ 2000\ mm

Resistance is given by

\Rightarrow R=\dfrac{\rho l}{A}\\\\\text{Insert values}\\\\\Rightarrow R=4.9\times 10^{-4}\times \dfrac{2000}{0.7}\\\\\Rightarrow R=1.4\ \Omega
