 ===Approximations & Assumptions===
-  * There are no other circuit elements (except for the wire).
+  * There are no other circuit elements (except for the wire): This simplifies down the model, having resistors or other capacitors will change the graphs for a charging or discharging capacitor.
-  * The wire itself has a small resistance, just so we do not have infinite current at $t=0$.
+  * The wire itself has a small resistance: If the wires had no resistance then the current at $t=0$ would go to infinity by ohms law. This can be shown by solving ohms law for current in a circuit as the resistance approaches zero.
-  * Practically speaking, the capacitor becomes "fully charged" (with respect to the potential of the battery) at some finite time.
+  * Practically speaking, the capacitor becomes "fully charged" (with respect to the potential of the battery) at some finite time: The amount and time it takes for a capacitor to charge also depends on the circuit it is in and the voltage across it, this assumption simplifies down our graphs.
