Inductance

maker

Inductance is the property of an electrical conductor by which a change in current generates an electromotive force (EMF) in the conductor itself and in any nearby conductors due to electromagnetic induction.

expanded

Inductance quantifies the ability of a coil or conductor to induce voltage as a result of a change in current flow. Expressed in henries (H), a high inductance value indicates a greater ability to store energy in a magnetic field. Practical applications include transformers and inductors in circuits for regulating current flow or storing energy, critical in power supply systems and electronic filters.

examples

An inductor with an inductance of 10 mH (millihenries) in a low-pass filter circuit, reducing high-frequency noise.

Commonly used in radio frequency (RF) filters to limit interference and stabilize signal transmission.

A transformer utilizing high inductance coils for voltage step-up from 230 V to 11,000 V.

Widely used in electrical substations to elevate voltage levels for efficient transmission over long distances.
