Imagine you are in line to enter a brand new shopping mall and you are very much excited because after months of waiting, you will now be able to enter shopping malls after the pandemic. The stores comprising the mall are very popular. These stores include Converse, Gucci, Jansport, Fendi and all other popular brands, and so the demand to enter is very high. Security guards only allow one person through the doors at a time. As a result, the line and the wait are quite long. To add to the chaos, the waiting crowd is made mostly of frequent shoppers who are growing very impatient and holding up the line with their constant complains. Together, these factors affect the flow of customers into the shopping mall, just as electric resistance affects the flow of charges through a current. 1. What makes less resistance favorable in a circuit? 2.If the guard formed two adjacent lines to allow two people into the mall at a time, we would expect the mall to be filled up faster. If we encased these two lines within a wire, the wire would be wider and shorter than the original. In terms of flowing electros why are wider and shorter wires favorable over narrow, long ones? 3.Compare the impatient shoppers to insulator in a circuit. What do insulators do to current flow? Are insulators necessarily bad for the circuit? (Hint: How they are helpful to humans?) Which type of material is commonly used as an insulator? 4.The type of customers (patient or impatient) the line is made up of will determine how orderly or chaotic the shopping mall is. Most wires are made up of what type of material and why? Name some examples of this material that are ideal for wires. 5.Let’s say security manages to calm down impatient shoppers with coupon offers. The environment becomes less heated and so the line becomes orderly. Therefore, do you think cooler wires have less resistance than warmer wires? Why or why not?
