So what is the Capacitor?
The capacitor is one of the passive components like a resistor. The capacitor is generally used to store the charge. In capacitor, the charge is stored in the form of an “electrical field”. Capacitors play a major role in many electrical and electronic circuits.
Generally, a capacitor has two parallel metal plates which are separated to each other. The two plates in the capacitor are separated by a non-conducting material.
There are different types and different shapes of capacitors available, from very small capacitors which are used in resonance circuits to large capacitors for stabilizing HVDC lines. But all capacitors are doing the same work that is storing the electrical charge and discharge.
The shape of a capacitor can be the rectangular, square, circular, cylindrical, or spherical shape. Unlike a resistor, an ideal capacitor does not dissipate energy. As the different types of capacitors are available different symbols were available to represent them which are shown below.

- Tuning – In a radio system.
Also, there are different types of capacitors available, we will see in brief in next blog.
FAQs for Capacitor
What is a capacitor?
A capacitor is an electronic component that stores electric charge and energy in an electric field. It consists of two conductive plates separated by an insulating material called a dielectric.
What are the types of capacitors?
There are many types of capacitors, including ceramic capacitors, electrolytic capacitors, tantalum capacitors, film capacitors, and supercapacitors. Each type has different characteristics and is used for different applications.
What is capacitance?
Capacitance is the measure of a capacitor’s ability to store electric charge. It is measured in farads (F).
How does a capacitor work?
A capacitor works by storing charge on its plates. When a voltage is applied across the plates, electrons are forced onto one plate and removed from the other plate. This creates an electric field between the plates, which stores the energy.
What is the maximum voltage rating for a capacitor?
The maximum voltage rating for a capacitor is the maximum voltage that the capacitor can withstand without breaking down. It varies depending on the type and size of the capacitor.
