15 Pоints An incаndescent lightbulb uses а length оf thin tungsten wire аs the filament. One particular lightbulb has a 0.22-meter length оf the tungsten wire used as its filament. This tungsten wire filament has a resistance of 19 ohms at a temperature of 20ºC. The tungsten wire filament has a resistance of 240 ohms when this bulb is operated at a potential difference of 120 volts. What is the power output of the lightbulb when connected to a 120 V source? Determine the cross sectional area of the wire. How much will it cost to run this lightbulb for 8 hours a day for 30 days if the cost of electricity is $0.15 / kWh? The bulb is replaced with a different one that has the same amount of filament, but has been stretched to 0.66 meter length. What is the new power output of the bulb when connected to a 120 V source
