A power plant produces energy at a voltage of Vi = 19491 V. Before being sent along long distance power lines this electricity is sent through a transformer with 147 turns in the primary coil and 6611 turns in the secondary coil.
Question 1: What is the voltage of the electricity sent through the long distance wires?
Question 2:If the wires have an efficiency of 99.60% and a resistance of 1355 Ω, what current flows through these wires?
For question 2 the answer is not 0.996*(voltage in question 1/1355) its something else.
