Induktorn

Induktorn is a fundamental passive electronic component that stores energy in a magnetic field when electric current flows through it. It is typically constructed by winding a coil of wire around a core, which can be made of air, iron, or other ferromagnetic materials. The primary characteristic of an inductor is its inductance, measured in Henries (H). Inductance quantifies the inductor's ability to oppose changes in electric current.

When the current flowing through an inductor changes, a voltage is induced across it. This induced voltage is proportional to the rate of change of the current and the inductance value. This phenomenon is known as self-induction. Inductors are used in a wide variety of electronic circuits. They are essential components in filters, oscillators, transformers, and energy storage circuits like those found in switching power supplies. In filters, inductors can be used to block high-frequency signals while allowing low-frequency signals to pass, or vice versa, depending on their configuration with capacitors. Their ability to store and release energy makes them crucial for smoothing out voltage fluctuations and stabilizing power delivery. The behavior of an inductor is described by Faraday's law of induction and Lenz's law.
