+ | - How does the current compare in the filament and carrier wires? (Same, bigger, smaller?) How does the electric field, potential difference, and power compare for the different wires? | ||
+ | - What is the drift speed of the electrons in the wire? How long would it take one electron to travel the whole circuit? (You can calculate a numbers here.) Why would the lights turn on immediately when you flip a switch? | ||
+ | - What assumptions did you make in your solution? Why did you need them? | ||
+ | - What other factors might influence the choice of metal? How realistic is your solution? | ||

In part thanks to your brilliant work with the lightbulbs and JPL, the Artemis 13 Spacecraft was able to have a successful launch. While on the way to the moon, disaster strikes. Among other things, the air filtration system seems to be malfunctioning. Team leader Melissa Lewis decides Artemis 13 needs to go home ASAP. Just as she gives the order to rotate boosters in order to send the ship home, the crew feels the spacecraft rock violently and warning lights start going off everywhere. The command ship starts to lose all of its power (maybe it had something to do with not being able to get the special tape from the STICKYSTUFF corporation at Lakeview).

+ | Conceptual Questions: | ||
+ | - How can you tell if two resistors are in series? Out of current, resistance, & voltage, what would HAVE to be the same for resistors in series? What would be different? | ||
+ | - How can you tell if two resistors are in parallel? Out of current, resistance, & voltage, what would HAVE to be the same for resistors in parallel? What would be different? | ||
+ | - How would you come resistors (series or parallel) to decrease the total resistance? What about to increase the resistance? | ||
+ | - What is the loop rule in circuits? What conservation principle is it related to? | ||
+ | - What is the node rule in circuits? What conservation principle is it related to? | ||
