1. The problem statement, all variables and given/known data A power plant produces energy at a voltage of Vi = 12693 V. Before being sent along long distance power lines this electricity is sent through a transformer with 166 turns in the primary coil and 6917 turns in the secondary coil. The voltage of the electricity sent through the long distance wires is 528900V. If the wires have an efficiency of 99.30% and a resistance of 1089 Ω, what current flows through these wires? 2. Relevant equations I have used V=IR. Of which I got V to be 485.67 and I mil 3. The attempt at a solution I got I = V/R to be 485.67 and I multiplied it by 0.993 in order to determine the current flowing through these wires. But I got it wrong. I don't seem to understand what is wrong. Did I use the correct equation? Or was my computation of efficiency incorrect?
