This problem has 3 parts.
The power company wants to deliver electrical service of 110 volts plus or minus 5 volts (105 to 115 volts), at 60 hertz frequency across a 10 kilometer transmission line to a small town. The transmission line voltage is 4,000 volts. There is a transformer available with a primary coil of 15,000 turns and secondary coils of 82 , 132, 164 and 187 turns.
part a - Which, if any, of the secondary coils can be used to deliver the power within the 105 to 115 volt range, include your calculations
part b - If a transformer is used that delivers an exact 110 volts, and the town requires a peak (maximum) of 800 kilowatts of power, how much current will flow through the 10 kilometer transmission line during the peak.
part c - Is a transformer has a secondary coil of 220 turns, how many turns are needed on the primary coil to get the 110 volts with an error of less than 1 percent?

A concrete service owns 3 mixer trucks to deliver concrete to
work sites in a local area. For each order, a truck is loaded and
weighed with mix at the single station for the order. Then the
truck makes the delivery and returns for the next load. Assume that
there is always an order for each truck. The delivery times are 15
minutes plus an exponential amount with mean 30 minutes and
load/weigh times are 8 minutes. This is a...

This problem has 3 parts.
A single resistor with resistance R ohms is connected to a
battery.
part a - If the single resistor is replaced with 2 identical
resistors each of R ohms connected in series, will the battery have
to provide more power, less power or the same? Explain your choice,
include any equations that apply.
part b If instead of connecting the two resistors in series,
they are connected in parallel, will the battery have to provide...

A certain electric power company maintains that its average rate
of critical home electrical power failures is 1.3 failures per day.
From analyzes carried out in previous years, it is known that
critical failures appear according to a Poisson process. The
failure repair team in electrical networks of that company
maintains that the failure rate received per day is higher and
chooses to make a count of the number of failures reported to it
during the month of May to...
