Why is electricity distributed using extremely high voltages?
A) To keep current as low as possible and reduce loss through the lines.
B) Higher voltages are easier to generate than lower voltages, so distributing them as a high voltage reduces equipment and saves money.
C) High-voltage electricity travels faster than lower-voltage electricity and can get from one side of the country to the other in seconds.
D) For safety because the insulation on the electrical distribution lines is not as effective at lower voltages.

What will be an ideal response?
An entrepreneurial electrical engineer has approached a large utility with a proposal that promises to reduce the utility’s power bill by at least 15% per year for the next 5 years through installation of patented surge protectors. The proposal states that the engineer will get $20,000 now and annual payments that are equivalent to 75% of the power savings achieved from the devices. Assuming the savings are the same every year at 15% and that the utility’s power bill is $1 million per year, what would be the equivalent uniform amount for years 1 to 5 of the payments to the engineer at an interest rate of 6% per year?
