How does Capacitor Work?

The answer is simple: capacitors store energy in an electric field.

Although not a common word in English, the capacitor has been used since ancient times to mean "an object that can store electrical charge."

A capacitor stores electricity using two closely-spaced conductive plates separated by a non-conductive material that acts as an insulator between them (in other words, it keeps the electricity from leaking away).

You first need to understand that when an electric charge moves through a conductor, it creates a magnetic field around it.

An electric charge moving through a wire makes a magnet inside the wire, which attracts the same kind of charge that's flowing through the wire.

The purpose of a capacitor is to store electrical energy in an electric field. This energy can be easily accessed anytime by reversing the current direction through the device.

What happens when we connect the capacitor and battery?


When the two components are connected in series, the resulting voltage is twice that of the combined batteries. When connected in parallel, the resulting voltage is four times that of the individual batteries.

Capacitors can slow down the flow of current in a circuit.


What is the Main use of capacitors?

Capacitors can delay the flow of electrons in a circuit, which makes them useful in high-current applications such as televisions, radios, and motors

Capacitors can also be combined with inductors (another electronic component) to create switches.

They can also reverse the direction of current flow in a circuit (often called a "rectifier" or "demagnetizer").

This process is why you see many old radios and television sets with capacitors on the back.

Capacitors can store large amounts of energy, making them useful in electronics and industrial machinery. They can also serve as a short-circuit switch to prevent a dangerous build-up of electrical charge.

Capacitors sometimes filter the incoming signal before passing it along to another component.

Capacitors are often used in electronics because they store large amounts of electrical energy for very little weight or volume. They're also widely used in industrial equipment to produce sudden bursts of power or to act as a short circuit breaker when there's a dangerous build-up of static electricity.

Most of us don't think about it too much, but capacitors are everywhere. They are one of the most important components of our modern world.
