If we want to make a coil consisting of an aluminum wire of length (100 m), so that it carries a current of (5 A), when the potential difference between its ends is (220 V), what is the value of: 1. Wire resistance? 2. Wire cross-sectional area? 3. The lost power in the wire when the current flows in it? Note that the resistivity of Aluminum is (2.8 x 10- Qm).
