Physics

This problem has 3 parts.

The power company wants to deliver electrical service of 110volts plus or minus 5 volts (105 to 115 volts), at 60 hertzfrequency across a 10 kilometer transmission line to a small town.The transmission line voltage is 4,000 volts. There is atransformer available with a primary coil of 15,000 turns andsecondary coils of 82 , 132, 164 and 187 turns.

part a - Which, if any, of the secondary coils can be used todeliver the power within the 105 to 115 volt range, include yourcalculations

part b - If a transformer is used that delivers an exact 110volts, and the town requires a peak (maximum) of 800 kilowatts ofpower, how much current will flow through the 10 kilometertransmission line during the peak.

part c - Is a transformer has a secondary coil of 220 turns, howmany turns are needed on the primary coil to get the 110 volts withan error of less than 1 percent?
