Suppose that electrical energy costs about $0.098/(kW · hour) (that is what you pay your local electric company). In a recent month the author's electric bill was $135. (Use 30 days as the length of a month.)
(a) If the electric potential provided by the electric company was 120 V, what was the average current in all circuits in the author's house?
(b) How many electrons did the author "purchase" from the electric company during this month?
