Problem #15) Given a 75 Watt, 120 Volt incandescent light bulb used in a lamp; a) Determine the resistance of the light bulb. b) If the lamp is used an average of 8 hours a day, determine the yearly cost of using the lamp assuming that the cost per kW.h is ten cents. c) If the light bulb is replaced with a 22 Watt, 120 Volt compact fluorescent light bulb, determine the amount of money saved annually if the lamp is still used for 8 hours a day. R= Yearly Cost = $ Annual Savings = $ (2)
