Yesterday the 5th grade came up with a really good analogy for resistors in an electrical circuit. Resistors (electrical components that resist the flow of electricity are measured in Ohms Ω). The analogy had to explain how you can add resistors in a parallel circuit (a circuit that allows many possible paths for electrons to flow) and the resistance actually drops. Using these same resistors in a series circuit (a circuit that electronics have no choice where to go other than pass through each resistor in order - in a series 1,2,3…) we see the resistance increase. How is possible to start with the same voltage and same resistors and the result would be so different?
The analogy is that each resistor is a small diameter coffee stir straw. If you put one to your mouth and tried to breathe then you would be able to, but it would be hard and not much air would flow through the straw. If you added more straws by putting one in the end of the other until you had a longer straw of the same diameter then it would be even harder to breathe through that long narrow tube (series circuit) as each air molecule has to go through each straw - one after the other. It would be much easer to breathe if you took those same straws and put them side by side and allowed yourself to breathe through all of the straws at once which gives the air more paths in and out of your mouth.
