 WEP practice problems (KEY) (note: Question 13 has a missing part that deletes itself when I make the test...and I don't know why. The info you need to answer problem c is that the output power of the bus is 70.0 kW. The efficiency is 35%. The missing question asked you to calculate an input power to the bus, which is 200 kW)
