Its primary function is to store electrical energy and release it when needed. Capacitors are widely used in electronic devices, power systems, and communication networks. In this article, we will explore the purpose of a capacitor in a circuit and how it contributes to the overall functionality of electrical systems.
When a voltage is applied across the plates, an electric field is created, causing electrons to accumulate on one plate while the other plate develops a positive charge. This process allows the capacitor to store electrical energy in the form of an electrostatic field.
In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
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.
When a voltage is applied to a capacitor, it starts charging up, storing electrical energy in the form of electrons on one of the plates. The other plate becomes positively charged to balance things out. This charge separation creates a voltage potential between the two plates and an electric field between the plates, storing the energy.
Unlike a resistor, capacitors do not dissipate energy – they do the opposite and store it. Capacitors are two-terminal passive components that are used in the majority of electrical circuits and systems that you come across. What makes capacitors so useful and stand out from other components is their ability to store energy.
