-==== Project: Austin, we have a snafu ====
+===== Project: Lakeview, we have a snafu =====
-With your help, the FTOE staff have repaired the damage and are almost ready to restart the hawkion accelerator.  However, they had to cut the lab systems off from Lakeview completely to ensure Manny can't hack in again and do more damage.  The onsite backup generators provide enough power for the lab, but when the FTOE staff tried to power up the control systems they discovered that several critical circuit boards used to generate the hawkion beam got fried during the emergency.  As a result, you need to create a new circuit that will allow you to provide different amounts of energy to various important systems.
+==== Kick Off Questions ====
+  - If capacitors are combined in series does that increase or decrease the total capacitance? What about parallel capacitors?
+  - Draw the I vs t, V vs t, and Q vs t graphs for charging & discharging the capacitors.
+  - Why is it important to have a current limit in circuits? (What happens to wires if there is a very high current?)

-The hawkion generator consists of an initiator beam and a set of focusing horns, which have a total resistance of 65 $\Omega$.
+The hawkion generator has a total resistance of 65 $\Omega$, and includes an initiator beam and a set of focusing magnets.
-The focusing horns require a short burst of 200 J to power-up.
+The focusing magnets require a short burst of 200 J to power-up.
 The initiator beam requires a short burst of 300 J to power-up.
-You need to be able to deliver different amounts of power to the generator; however, you are not sure that the 100 V primary power supply in the particle generator will be sufficient to power these systems. You manage to find some additional batteries (three 10 V batteries from the supply room) to use if you need them.

-You also have several 0.125F capacitors and resistors (1 $\Omega$, 5 $\Omega$, 10 $\Omega$, 50 $\Omega$, 100 $\Omega$) on hand.

 You also have access to multiple switches that can be used to open and close parts of the circuit you are designing.

-Conceptual Questions:
+==== Wrap Up Questions ====
   - Where did you place switches in your circuit? What positions do they need to be in to charge & discharge the capacitors?
   - How did you limit the current to be under 2 A?
-  - Why is it important to have a current limit in circuits? (What happens to wires if there is a very high current?)
+  - What assumptions did you make in this problem? Why did you need to make them?
-  - If capacitors are combined in series does that increase or decrease the total capacitance? What about parallel capacitors?
+  - Suppose you have a 9 V battery connected in series to a capacitor and resistor. If the capacitor is initially uncharged, what is the voltage on that capacitor? What is the voltage on the resistor? If the capacitor is fully charge, what is the voltage on the capacitor? What is the voltage on the resistor?
-  - Draw the I vs t, V vs t, and Q vs t graphs for charging & discharging the capacitors.
+  - If you wanted to increase the capacitance in your circuit, name 3 ways that you could increase the total capacitance.
-  - What assumptions did you make in this problem?
