Inductance is a physical quantity that characterizes the ability of an electrical conductor, such as a coil, to induce an electromotive force (voltage) due to a change in the current flowing through it. This property reflects how effectively a coil can store magnetic energy in its magnetic field. While the Henry (H) is the SI unit for measuring inductance, the concept extends beyond coils, influencing how circuits respond to changes in current, affecting their behavior in AC circuits, filters, transformers, and various types of electromagnetic devices. Inductance plays a crucial role in designing and operating a wide range of electrical and electronic systems, influencing their functionality and performance.
