A power plant produces a voltage of 6.0 kV and 150 A. The voltage is stepped up to 250 kV by a transformer before it is transmitted to a substation. What is the current in the transmission line from the plant to the substation?
A hydroelectric dam produces power that is stepped up to a
potential difference of 240kV. There is a 0.60% loss of power
due to transmission through a wire with a total resistance of
0.50

How much power does the dam produce? Assume there is
no energy lost in the step-up transformer. * The actual answer
is 690MW (megawatts); I just don't know how to solve it.
