HOW A CAPACITOR WORKS Goal: This is an exploration of what happens when a battery that provides a fixed potential difference V is connected to a light bulb or a capacitor/lightbulb combination. We are ultimately interested in understanding the charging and discharging of a capacitor and how it behaves as you connect it with other components. These components can be the light bulbs or the resistors provided in the kit. Using the iOLab, you will find how the capacitor charges as a function of time
