Suppose a large power plant generates electricity at 12.0 kV. Its old transformer once converted this voltage to 315 kV. The secondary coil of this transformer is being replaced so that its output can be 730 kV for more efficient cross-country transmission on upgraded transmission lines.
Randomized Variables
Vi = 315 kV
V2 = 730 kV
(a) What is the ratio of turns in the new secondary to the number of turns in the old secondary?
(b) What is the ratio of new current output to the old current output for the same power input to the transformer?
