Answer:
[tex]R=2.42\times 10^{-7}\ \Omega[/tex]
Explanation:
We have,
Dimension of the sheet is 7 cm × 22 cm.
Length of the tube, l = 22 cm
Resistivity of the copper wire is [tex]\rho=1.7\times 10^{-8}\ \Omega-m[/tex]
It is required to find the resistance between the ends. We know that the formula of resistance is given by :
[tex]R=\rho \dfrac{l}{A}[/tex]
A is area of sheet
[tex]R=1.7\times 10^{-8}\times \dfrac{0.22}{0.07\times 0.22}\\\\R=2.42\times 10^{-7}\ \Omega[/tex]
So, the resistance between the ends is [tex]2.42\times 10^{-7}\ \Omega[/tex].
