6 FAQs about [Power inductor energy storage inductor]

What does an inductor do?

An inductor is a component in an electrical circuit that stores energy in its magnetic field. Inductors convert electrical energy into magnetic energy by storing, then supplying energy to the circuit to regulate current flow. This means that if the current increases, the magnetic field increases. Figure 1 shows an inductor model.
