Indüktör

Indüktör, 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 one of the three fundamental passive linear circuit elements, alongside resistors and capacitors. An inductor typically consists of a coil of wire, often wound around a core made of ferromagnetic material or air. The primary function of an inductor is to oppose changes in electric current. This property is called inductance, measured in henries (H).

When the current through an inductor changes, it induces a voltage across the inductor that opposes this change. This phenomenon is described by Faraday's law of induction and Lenz's law. The amount of inductance depends on the number of turns in the coil, the geometry of the coil, and the magnetic permeability of the core material. Inductors are used in a wide variety of electronic circuits, including filters, resonant circuits, transformers, and energy storage in switching power supplies. They play a crucial role in controlling and shaping electrical signals by their ability to store and release magnetic energy.
