Transcribed Image Text:A power plant needs to generate Po= 340MW of power for a city 10km away. The city power outlets need to operate at 120V.
Part A
One idea might be to run the power lines at 120V so homes can directly tap into the power lines. What is the current needed to do this? (Hint: use P-IV).
