The current in a 120-V reading lamp is 2.4 A. If the cost of electrical energy is $0.090 per kilowatt-hour, how much does it cost to operate the light for an hour? (Do not round to the nearest cent.)

In your problem which ask to calculate how much does it cost to operate a light for an hour is the current in a lamp is 120V and has a current of 2.4 A. The cost of electrical energy is $0.09 per kilowatt hours, so with that dat itself, the possible in terms of cents is actually 3 cents
