| Lieutenant Maverick Mitchell has been impressed with your work over at JPL and has been considering hiring your team as permanent consultants. Maverick was all ready to sign the hiring paperwork, but just got word that NASA director Dr. Sinnay Tobb requires some extra vetting. Dr. Tobb has passed along the following tasks to test your mettle. Complete the levels and show that you're ready to be permanent consultants! | Lieutenant Maverick Mitchell has been impressed with your work over at JPL and has been considering hiring your team as permanent consultants.

| + | === Learning Goals: === | ||
| + | * Explain how you know something is in series. Explain what happens for current & voltage when resistors are in series. | ||
| + | * Explain how you know something is in parallel. Explain what happens for current & voltage when resistors are in parallel. | ||
| + | * Explain what the loop rule is and the physical principle it is related to. | ||
| + | * Explain what the node rule is and the physical principle it is related to. | ||
| + | * Apply V = IR & P = IV to solve for any unknown quantities in the circuit (P, I, V, & R). | ||
| + | * Calculate the total combined resistance for a given circuit. | ||

| + | Conceptual Questions: | ||
| + | - What are the circuit rules that you used to solve these circuits? When did you use each of them? | ||
| + | - How do you know if something is in series or parallel (or neither)? What happens to current & voltage in each of those cases? | ||
| + | - What are the loop & node rules? What physical principles do they relate to? | ||
| + | - The equation for power can be written in 3 different ways - what are the 3 ways & how do you get them? | ||
| + | - What assumptions did you make when solving these circuits? (Hint: there are at least 3 big ones.) | ||
