+=== 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.)
