1. A 250 m, 2 wire D.C. distributor fed from one end is located uniformly at the rate of 1.6 A/metre. The resistance of each conductor is 0.0002 ohms per metre. Find the voltage necessary at feed point to maintain 250 V
i). At the far end
ii). At the mid-point of the distributor
2). Derive an expression for the power loss in a unifoimly loaded distributor fed at one end.
