When the capacitor is discharging, the electron excess on the negatively charged plate starts to flow to the positively charged plate, which causes the capacitor to create an electron flow in the circuit and act as a voltage source for a period of time. What factors affect the charging and discharging rate of a capacitor?
In figure (a), an uncharged capacitor has been illustrated, because the same number of free electrons exists on plates A and B. When a switch is closed, as has been shown in figure (b), then the source, moves electrons towards B via the circuit. In this way, the flow of electrons starts from plate A, and electrons start to store on plate B.
The same ideas also apply to charging the capacitor. During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply.
Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure.
