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).

+ | a) Are there places in your circuit that can simplify? (AKA resistors in series or in parallel?) | ||
+ | |||
+ | b) Redraw the circuit after making the simplifications that you can. | ||
+ | |||
+ | c) How many different currents do you have in your circuit? Draw and label this on your picture. What node rule equations can you make? | ||
+ | |||
+ | d) How many different loops do you have in your circuit? What loop rule equations can you make? | ||
+ | |||
+ | e) Solve for your unknown currents. Note: you can use Wolfram Alpha or other resources online to solve the system of equations. | ||
