An Electric Lamp Can Be Modelled As A Resistor Four Electrical Halogen Light Bulbs Lamps Will Be Used To Illuminate A 1 (30.35 KiB) Viewed 17 times
An electric lamp can be modelled as a resistor. Four electrical halogen light bulbs (lamps) will be used to illuminate an area of 100 m². A light intensity of 40 lm/m² is needed. Light bulbs can supply 20 lm/W at 220V. What should be the power of each lamp to illuminate the area? What is the current and resistance of each lamp?
