摘　　要：讨论了Multisim9在灯泡串并联电路中的应用。利用Multisim9元件库中的小灯泡,将不同规格灯泡串并联,观察灯泡明暗变化情况,得到灯泡明暗与其实际消耗的功率大小有关。实际功率越大,灯泡越亮。通过预设灯泡的断路故障,学会对电路串并联电路作相应的电路分析。在教学中将Multisim9与灯泡串并联电路结合起来,观察直观形象,有益于提高学生对电学知识的理解。In this paper,the application of Multisim9 in bulb series-parallel circuits is discussed.Using the small light bulbs in the Multisim9 component library,the bulbs of different specifications are connected in series and parallel to observe the change of the brightness of the light bulb,which gives the result that the brightness of the light bulb is related to the actual power consumption.The higher the actual power,the brighter the bulb.By presetting the disconnection fault of the bulb,students can learn to analyze the series circuit and parallel circuit.In the teaching,Multisim9 combined with the bulb serial-parallel circuit can been observed visually,which is beneficial to improve students’understanding of electrical knowledge.
