Induktivitätswerte

Induktivitätswerte, often referred to as inductance values, represent a fundamental electrical property of a component, typically a coil of wire. This property quantifies how effectively a component can store energy in a magnetic field when an electric current flows through it. The standard unit for inductance is the Henry (H), named after the American physicist Joseph Henry. A higher inductance value indicates a greater ability to store magnetic energy.

The inductance of a coil is influenced by several factors, including the number of turns in the coil, the geometry of the coil (such as its length and diameter), and the magnetic permeability of the core material around which the wire is wound. Materials with high magnetic permeability, like iron, will increase the inductance compared to an air core. Inductance is an AC parameter; it describes the opposition to a change in current. When the current is changing, a voltage is induced across the inductor, which opposes this change.

In practical applications, inductors with specific inductance values are used in a wide range of electronic circuits, including filters, resonant circuits (like those in radio tuners), and power supply circuits for energy storage and smoothing. The precise inductance value is crucial for the correct functioning of these circuits. For example, in a resonant circuit, the inductance and capacitance work together to determine the resonant frequency.
