A wire of given metarial having length l and ares of cross-section A has a resistance of `4 Omega`. What would be the resistance of another wire of the same meterial having length l/2 and area of cross-section 2A ?

Explanation

To find the resistance of the second wire, we will use the formula for resistance, which is given by:

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

where:
- \( R \) is the resistance,
- \( \rho \) is the resistivity of the material,
- \( L \) is the length of the wire,
