In the first two parts of this experiment, we observe that when we flip the switch, thevoltage first very quickly changes to one value, then slowly changes after that. Let's examinehow to explain this.● Suppose the wire has a 10Ω resistance (which is almost certainly an overestimate) andthe voltmeter has a 1MΩ resistance (1Ω=1s/F). Given that our capacitances are of order~10μF, compute the time constant for each resistance: this is essentially the time it takesfor current to "go through" that component. From these timescales, consider: of the twoprocesses described above (the quick change in voltage and the slow change in voltage),which process is controlled by each component's resistance?
