Reference no: EM132782702

Some children are afraid of the dark and ask their parents to leave the hall light on all night. Suppose the hall light in a child's house has two 60.W bulbs (120W total), the voltage is 120V, and the light is left on for 8.0 hours.

(a) How much current flows through the light fixture?

(b) How many kilowatt-hours of energy would be used in one night?

(c) If the power company charges 8.0 cents per kilowatt-hour, how much does it cost to leave the light on overnight?

(d) If the two 60W bulbs are replaced by compact fluorescent bulbs that use 13W each, how much money would the family save each night?
