What length of a copper wire of cross-sectional area `0.01 mm^2` will be needed to prepare a resistance of `1 kOmega`? Resistivity of copper `= 1.7 xx 10^(-8) Omega m`.

Explanation

To find the length of a copper wire needed to prepare a resistance of \(1 \, k\Omega\) with a given cross-sectional area and resistivity, we can use the formula for resistance:

\[ R = \frac{\rho L}{A} \]

Where:
- \(R\) is the resistance,
