Can you please answer the question!! THE ANSWERS ARE NOT 18.4 W OR 39.1 W!!!!
A large power plant generates electricity at 12.0 kV. Its old transformer once converted the voltage to 315 kV. The secondary coil of this transformer is being replaced so that its output can be 725 kV for more efficient cross-country transmission on upgraded transmission lines. V1 = 315 kVV2 = 725 kV What is the ratio of turns in the new secondary to the number of turns in the old secondary? What is the ratio of new current output to the old current output for the same power input to the transformer? If the upgraded transmission lines have the same resistance as the original ones, what is the ratio of new line power loss to the old?
