AI Customer Serviceenergy 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
This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero.
When a capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the capacitor is fully discharged as there is no charge stored across it. The rate of decrease of the potential difference and the charge will again be proportional to the value of the current.
As the capacitor charges the charging current decreases since the potential across the resistance decreases as the potential across the capacitor increases. Figure 4 shows how both the potential difference across the capacitor and the charge on the plates vary with time during charging.
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.
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
