AI Customer ServiceDuring capacitor discharging, both the voltage and current exponentially decay to zero. In contrast, during capacitor charging, charge is accumulated on the capacitor. Capacitor charging and discharging are related to the charge. Capacitor charging means the accumulation of charge over the capacitor, while capacitor discharging means the reduction of charge from the capacitor plates.
This charging (storage) and discharging (release) of a capacitors energy is never instant but takes a certain amount of time to occur with the time taken for the capacitor to charge or discharge to within a certain percentage of its maximum supply value being known as its Time Constant ( τ ).
The charging of a capacitor is not instant as capacitors have i-v characteristics which depend on time and if a circuit contains both a resistor (R) and a capacitor (C) it will form an RC charging circuit with characteristics that change exponentially over time.
Conversely, when discharging, the voltage and charge decrease over time, following an exponential decay. The current also decreases, mirroring the reduction in charge and voltage. These curves are critical for visualising and understanding the charging and discharging processes of a capacitor.
The instantaneous voltage, v = q/C. q – instantaneous charge q/C =Q/C (1- e -t/RC) q = Q (1- e -t/RC) For a capacitor, the flow of the charging current decreases gradually to zero in an exponential decay function with respect to time.
When a capacitor is charged, it behaves like an open circuit and there is no current flowing through it, having a maximum voltage across it of the voltage of the charging source. For instance, if the capacitor below is charged by a voltage source E, the voltage across the capacitor will be raised to voltage E.
