| - | * Whenever we measure energy, the capacitor is charged and and there is no longer current in the circuit. | + | * Whenever we measure energy, the capacitor is charged and and there is no longer current in the circuit: As a capacitor charges energy gets stored in the capacitor and this happens over time. We are only looking at the fully charged capacitor in this case. |
| - | * There is negligible resistance in the circuit, so the voltage across the capacitor is the same as in the battery. | + | * There is negligible resistance in the circuit: The voltage across the capacitor is the same as in the battery |
| - | * In the case that we disconnect the capacitor, it does not discharge at all. | + | * In the case that we disconnect the capacitor, it does not discharge at all: In reality capacitors are not perfect and lose their charge in a multitude of ways, but we will assume that is not happening in this problem. |
