Discussion post questions: link to video: https://youtu.be/ian6NyXpszw (national lampoons Christmas vacation - 250 strands of light uploaded by ghfggrr 1 minutes and 29 seconds long) 1.) In an earlier scene (not shown), Mr. Griswald explains that if one bulb doesn't work, then none of the bulbs in the same strand will light up, which means that the bulbs in each strand are connected in series. (This is not true about modern string of lights.) At the beginning of the video clip, he describes the magnitude of the light display he has installed. a.) Describe at least two reasons why it would be a bad idea to sting all 250 strands in series to form a single light circuit. b.) Describe evidence from the video that he did not, in fact, make a single light circuit. Based on what you can see, how many parallel light circuits do you suppose there are? 2.) For simplicity, let's assume that he slightly miscounted the number of strands and he had 16 parallel circuits, each containing 16 strands of 100 bulbs in series. If each bulb has electrical resistance R, then what would be the total resistance of the entire light display? 3.) When the lights finally go on, the power consumption is enormous (the city has to make use of auxiliary nuclear power). This makes for a funny scene, but of course it is not realistic. a.) Describe one or more reasons why we should expect the power consumption from the Griswald's Christmas lights not to be so large. Use clues provided in the video, such as the real reason why the lights actually turn on or off, as well as general information about household circuits and answers to the previous question. Estimate the maximum power that the entire display could draw. b.) Compare your estimate of the maximum power that the display would draw to the power requirements of other common appliances such as a clothes dryer (which uses a 240 V circuit)
