A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on: the voltage required to place this charge on the capacitor plates, i.e. the capacitance of the capacitor.
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. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then
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.
When a capacitor gets fully charged, the value of the current then becomes zero. Figure 6.47; Charging a capacitor When a charged capacitor is dissociated from the DC charge, as has been shown in figure (d), then it remains charged for a very long period of time (depending on the leakage resistance), and one feels an intense shock if touched.

Discharging and charging capacitors is that the capacitor''s have the capacity to both control and anticipate the pace at which they charge and discharge, which makes them valuable in electronic timing circuits.
