Suppose there are two transformers between your house and the high-voltage transmission line
that distributes the power. In addition, assume your house is the only one using electric power. At
a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage
from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the
primary of the transformer. The secondary is connected to the primary of another step-down
transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole.
The secondary of this transformer delivers a 240-V emf to your house. How much power is your
house using? Remember that the current and voltage given in this problem are rms values.
