A line transports electrical energy at a rate of 5x10 ^ 4 kw from its source (hydroelectric plant) to the city where it is consumed. The city is 50km away and the line has a resistance of 0.004 Ω per km. A) Find the electrical power loss in the line, if the ddp between both conductors is: i) 10 ^ 5 v, ii) 10 ^ 4 v, iii) 10 ^ 3 v, iv) 110 volt

An electric power distributor charges residential customers $0.10 per kilowatt-hour (kwh). the company advertises that "green power" is available in 150 kwh blocks for an additional $4 per month. (green power is generated from solar, wind power, and methane sources.) if a certain customer uses an average of 391 kwh per month and commits to one monthly 150 kwh block of green power, what is her annual power bill
