Capacitor Discharging
C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, VC. Conversely, a smaller capacitance value leads to a quicker discharge, since the capacitor can''t hold as much charge, and thus, the lower V C at the end.
