Today was mostly spent practicing our model of internal resistance and making our models for the ammeter and voltmeter clear. But we did spend a little time figuring out how capacitors act when completely uncharged and when they've been in the circuit for a long time. We also looked at what happened if we charged a capacitor with 3 D-cells versus 6 D-cells. It seems like a lot more energy is stored when a larger potential difference is across the two terminals.
