| You need to be able to deliver different amounts of power to this module; however, you are growing concerned that the power supply the probe has access to of 100 V may not be sufficient to power these probe systems. You manage to find some additional batteries onboard (three 10 V batteries from the supply room) to use if you need them. | You need to be able to deliver different amounts of power to this module; however, you are growing concerned that the power supply the probe has access to of 100 V may not be sufficient to power these probe systems.

| + | Conceptual Questions: | ||
| + | - Where did you place switches in your circuit? What positions do they need to be in to charge & discharge the capacitors? | ||
| + | - How did you limit the current to be under 2 A? | ||
| + | - Why is it important to have a current limit in circuits? (What happens to wires if there is a very high current?) | ||
| + | - If capacitors are combined in series does that increase or decrease the total capacitance? | ||
| + | - Draw the I vs t, V vs t, and Q vs t graphs for charging & discharging the capacitors. | ||
| + | - What assumptions did you make in this problem? | ||
