Charging and discharging a capacitor When a capacitor is charged by connecting it directly to a power supply, there is very little resistance in the circuit and the capacitor seems to charge instantaneously. This is because the process occurs over a very short time interval. Placing a resistor in the charging circuit slows the process down.
energy dissipated in charging a capacitorSome energy is s ent by the source in charging a capacitor. A part of it is dissipated in the circuit and the rema ning energy is stored up in the capacitor. In this experim nt we shall try to measure these energies. With fixed values of C and R m asure the current I as a function of time. The ener
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
Charging and Discharging of Capacitor with Examples- When a capacitor is connected to a DC source, it gets charged. As has been illustrated in figure 6.47. In figure (a), an uncharged capacitor has been illustrated, because the same number of free electrons exists on plates A and B.
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.
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.
