Physics

A generator at a utility company produces 100 A of current at4.0 x 103 V. The voltage is stepped up to 2.4 x 105 V by atransformer before being sent on a high voltage line across a ruralarea to a city. Assume the effective resistance of the line is 30.0Ω and the transformers are ideal.

a. Determine the percentage of power lost in the transmissionline.

b. What percentage would be lost if the voltage would not havebeen stepped up?

c. How many kW-hr of energy is lost each day if the voltagewould not have been stepped up?

d. Calculate the cost of this energy loss if the price ofelectricity is $.11/kW-hr.
