The charge and discharge of a capacitor
Discharging As soon as the switch is put in position 2 a ''large'' current starts to flow and the potential difference across the capacitor drops. (Figure 4). As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls
10.14: Discharge of a Capacitor through an Inductance and a …
Those familiar with differential equations will recognize that the nature of the solution will depends on whether the resistance is greater than, less than, or equal to (2sqrt{frac{L}{C}}). You can use the table of dimensions in Chapter 11 to verify that (sqrt{frac{L}{C}}) is dimensionally similar to resistance.
