1. The problem statement, all variables and given/known data A small town requires 1.00MW of electricity. The town is located 35 km away from power source. Electricity delivered at 120 Volts. (1) What current is required by the town? (2) Assume answer to part (1) is the current flowing along the transmission lines. Waste heat during transport equal 10% of energy delivered to town (waste heat = 0.10MW, total power = 1.10MW). What must the generator voltage be to supply power to town at 120V? (3) What diameter of copper wire is required to deliver electricity based on above conditions? (Resistivity of copper = 1.72*10^-8) (4) Introduce transformers. Assume copper wires are 0.100 m diameter and waste heat is 10% of power, again. Assume generator voltage is the same as part (2). Calculate transmission voltage and transmission current. Calculate turns ratio of step-up transformer at power plant. 2. Relevant equations P=IV P=I^2(R) 3. The attempt at a solution I tried the first part of the problem (hopefully I'm right). I=P/V I=10^6 W / 120 V = 8333A I'm stumped on the second part of the question and hence, I can't move on to the next parts... Any help is appreciated, thanks!
