1. The problem statement, all variables and given/known data A power station delivers 750 kW of power at 12,000 V to a factory through wires with total resistance 3 Ohm. How much less power is wasted if the electricity is delivered at 50,000 V rather than 12,000 V? 2. Relevant equations P=I x V, P= V^2/R, P=I^2 x R 3. The attempt at a solution With given V1 and R values Power comes as: P1= (12000)^2 / 3=48000kW, what is this 750kW then??? Is this station delivers power at 48000kW or 750kW?? Again, for V2 and R values: P2=(50000)^2 / 3=833333kW I would make the difference of figure P2 and P1 and obviously it's not right according to solution manual , but why? I'm totally lost.
