A capacitor is an electronic component to store electric charge. It is a passive electronic component that can store energy in the electric field between a pair of conductors called “Plates”. In simple words, we can say that a capacitor is a component to store and release electricity, generally as the result of a chemical action.
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
When a voltage V V is applied to the capacitor, it stores a charge Q Q, as shown. We can see how its capacitance may depend on A A and d d by considering characteristics of the Coulomb force. We know that force between the charges increases with charge values and decreases with the distance between them.
By placing capacitors at strategic locations in the circuit, designers can effectively smooth out voltage fluctuations and maintain a consistent voltage level, which is essential for the proper operation of electronic devices.
The main function of a capacitor is to store electric energy in an electric field and release this energy to the circuit as and when required. It also allows to pass only AC Current and NOT DC Current. The formula for total capacitance in a parallel circuit is: CT=C1+C2…+Cn.
The two terminals of the capacitors connect to the two tin plates separately. In the early ages, it used paper as a dielectric. As of now, the capacitors are using the materials like plastic sheets. That’s why it is called a “ paper capacitor “.
Capacitors store electric energy when they are connected to a battery or some other charging circuit. They are commonly placed in electronic components and are used to maintain a power supply while the device is unplugged and without a battery for a short time.
