10.14: Discharge of a Capacitor through an Inductance and a Resistance
The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor. Thus while the electric field in the capacitor diminishes, the magnetic field in the inductor grows, and a back electromotive force (EMF) is induced in the inductor. Let (Q) be the charge in the capacitor at some time. The current (I ...

Capacitor Charging
This affects the charging process in that the greater the resistance value, the slower the charge, while the smaller the resistance value, the quicker the charge, and, thus, the lower the amount of voltage, VC, across the capacitor. This is because resistance represents an impedement. It slows down and lessens current, so that charging is slower, and, thus, the resultant voltage …
