Calculate the resistance of `1 km` long copper wire of radius `1 mm`. Resistivity of copper is `1.72 xx 10^-8 Omega m`.

Text Solution

AI Generated Solution

To calculate the resistance of a 1 km long copper wire with a radius of 1 mm, we will use the formula for resistance in terms of resistivity: \[ R = \frac{\rho L}{A} \] where: - \( R \) is the resistance, - \( \rho \) is the resistivity of the material (copper in this case), - \( L \) is the length of the wire, ...
