Textbook Question
Chapter 6, Problem 11PEA
A power plant generator produces a 1,200 V, 40 A alternating current that is fed to a step-up transformer before transmission over the high lines. The transformer has a ratio of 200 to 1 wire loops, (a) What is the voltage of the transmitted power? (b) What is the current?

A transformer has 300,000 windings in its primary coil and uses 12,000V AC input.
How many windings would be needed to produce at output of 110V AC? Is this a step down or step up transformer?
B)E xplain why a transformer only works with AC and not DC currents.
The ratio of number of windings on the primary side to the number of windings on the secondary side of a transformer is 10:1. If the voltage on the orimary side is 120V, what would be the voltage on the secondary side?
A large power plant generates electricity at 12.0 kV. Its old transformer once converted the voltage to 325 kV. The secondary of this transformer is being replaced so that its output can be 760 kV for more efficient cross-country transmission on upgraded transmission lines. If the power output is 1,000 MW and line resistance is 1.85 Ω, what are the old and new line power losses (in MW)?
