(10%) Problem 7: Suppose a large power plant generates electricity at 12.0 kV. Its old transformer once converted this voltage to 345 kV. The secondary coil of this transformer is being replaced so that its output can be 760 kV for more efficient cross-country transmission on upgraded transmission lines. Randomized Variables Vi = 345 kV V2 - 760 kV 50% Part (a) If the overall power output is 1000.0 MW and line resistance is 2.00 2. what was the power loss, in watts, in the old power lines which left the plant? & 50% Part (b) If the overall power output is 1000.0 MW and line resistance is 2.00 , what is the power loss, in watts, in the new power lines which leave the plant?
