Introduction

For those who are starting world In electronics, it can be confusing to understand the difference between a capacitor and an inductor. Both components are used in electronic circuits, but they fulfill very different roles. In this article we will explain the differences between capacitor and inductor, and what they are used for in practice.

What is a capacitor?

A capacitor is a passive component that is used to store electrical charge. It consists of a pair of conductive plates separated by a dielectric, which can be air, paper, ceramic, plastic, among other materials. Capacitors are used in circuits to block DC or to filter out unwanted frequencies.

Capacitor applications

• They function as filters in electrical circuits to reduce noise or electromagnetic interference;
• They store electrical energy in the engine starting systems;
• They help stabilize the voltage in voltage regulator circuits.

What is an inductor?

An inductor is a passive component used to store magnetic energy in a magnetic field. It consists of a coil of wire that is wound around a ferrite or iron magnetic core. Inductors are used in circuits to filter or block alternating currents (AC), pass direct currents (DC), and to raise or lower voltage.

Inductor Applications

• They suppress noise in electrical and electronic circuits;
• They regulate the current in lighting circuits;
• They filter the frequency in audio circuits.

Conclusion

In short, a capacitor and an inductor are different components that perform different functions. Capacitors are used to store electrical energy and filter out unwanted frequencies, while inductors are used to store magnetic energy and filter out alternating currents, including other apps. Both components are essential in electronic circuits and their use depends on the specific design of the circuit in question.
