   - Her phone is never in direct contact with the battery.
   - The maximum current in the circuit (either charging or discharging) never reaches above 0.1 A.
-  - Her phone would receive 10 - 30 kJ of energy when the capacitors discharge.
+  - The capacitor(s) would need to discharge 10-30 kJ to charge her phone.
-In her emergency kit, Dr. Jackie has two switches, a variety of 10  $\Omega$ , 15  $\Omega$ , 20  $\Omega$ , and 25  $\Omega$  resistors, and a variety of 100 F, 200 F and 300 F capacitors. She has told you to add any of the elements wherever you need in the circuit, as long as it meets those conditions. In your final solution, make sure you include: a circuit diagram with your added elements, a demonstration of how your circuit meets the criteria, and an explanation of what you expect in the circuit at different points in time (i.e. when the switch opened/closed, where does current flow, is the capacitor charged/discharged at that point, charging/discharging graphs).

 Remember, a good solution includes explanations, diagrams, evaluations, and commentary in addition to your calculations. See the Project Write Up Rubric for more details.

 === Learning Goals: ===
   * Design a circuit using a switch that charges and discharges capacitors
-  * Determine how to combine capacitors in series/parallel to reach desired energy
+  * Use loop rule to determine voltage at different points in the circuit
   * Use resistors in series/parallel to control maximum current
+  * Determine how to combine capacitors in series/parallel to reach desired energy
   * Explain what happens in the circuit in terms of current/voltage/charge over time
