inductante

An inductor, also known as a coil or reactor, is a passive electrical component that stores energy in a magnetic field when electric current flows through it. It is typically made of a wire wound into a coil, often around a core of magnetic material. The inductance of an inductor is a measure of its ability to store energy in the magnetic field. It is denoted by the symbol "L" and is measured in henries (H).

Inductors are widely used in electronic circuits for various purposes. They are often used in filters to block direct current (DC) while allowing alternating current (AC) to pass. They are also used in oscillators to generate a specific frequency of AC. In power electronics, inductors are used in switching power supplies and motor drives to store energy and smooth out current.

The behavior of an inductor is described by Faraday's law of induction, which states that a changing magnetic field induces an electromotive force (EMF) in a conductor. This property is used in transformers, where an inductor (the primary winding) induces an EMF in another inductor (the secondary winding).

Inductors can be classified based on their construction and application. Air-core inductors have no magnetic core, while iron-core inductors have a core made of iron or other magnetic materials. Variable inductors have a movable core that can change the inductance. Chokes are inductors designed to block high-frequency signals while allowing low-frequency signals to pass.

Inductors are essential components in many electronic devices, from simple circuits to complex systems. Their ability to store and release energy makes them indispensable in various applications, from power supplies to communication systems.
