Induktancja
Induktancja, often denoted by the symbol L, is a fundamental electrical property of a circuit element, typically a coil of wire, that describes its ability to store energy in a magnetic field when an electric current flows through it. It is a measure of how much a change in current will induce a voltage in that same circuit element. The SI unit of inductance is the Henry (H), named after the American physicist Joseph Henry.
When the current in an inductor changes, it creates a changing magnetic flux. According to Faraday's law
Inductors are passive components used in a wide variety of electronic circuits. They are essential for filtering,
