The generator at a power plant produces AC at 29,000 V. A transformer steps this up to 355,000 V for transmission over power lines. If there are 2,150 turns of wire in the input coil of the transformer, how many turns must there be in the output coil?
Vin/Vout = Nin/Nout
or, (29000 V)/(355000 V) = (2,150 turns)/(Nout)
or, Nout = 26319 turns

An AC power generator produces 48 A (rms) at 3,600 V. The voltage is stepped up to 100,000 V by an ideal transformer, and the energy is transmitted through a long-distance power line that has a resistance of 146 Ω. What percentage of the power delivered by the generator is dissipated as heat in the power line? %

Suppose a large power plant generates electricity at 12.0 kV. Its old transformer once converted this voltage to 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 V 315 kV V2 730 kV - 50% Part (a) If the overall power output is 1000.0 MW and line resistance is 2.00 Ω, what was the power loss, in watts, in the old power...
A small generating station produces 5.0 kA of current at V 10.0 kV. It must be transmitted with only a 4.0 % loss of power, in a transmission line of 130 total resistance. To achieve this the voltage is changed by a transformer with 24 turns in its primary coil. How many turns are in the transformer's secondary coil?
