An inductor is a passive electrical component that stores energy in a magnetic field when an electric current passes through it. It typically consists of a coil of wire wound around a core, which can be made of air, iron, or other materials. The key properties of an inductor include: 1. **Inductance (L)**: This is the measure of an inductor's ability to store energy in the magnetic field, typically measured in henries (H).
