Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance which depends entirely on the geometry of the capacitor (the physical configuration of conductors).
The capacitance of a capacitor is the amount of charge that can be stored per unit voltage. The energy stored in a capacitor is proportional to the capacitance and the voltage. When it comes to electronics, the significant components that serve as the pillars in an electric circuit are resistors, inductors, and capacitors.
The energy stored in a capacitor is proportional to the capacitance and the voltage. When it comes to electronics, the significant components that serve as the pillars in an electric circuit are resistors, inductors, and capacitors. The primary role of a capacitor is to store a certain amount of electric charge in place.
Thus, the capacitor acts as a source of electrical energy. If these plates are connected to a load, the current flows to the load from Plate I to Plate II until all the charges are dissipated from both plates. This time span is known as the discharging time of the capacitor.
