Inductors vs Capacitors: A Comparative Analysis of Energy Storage

How Does an Inductor Store Energy? Inductors store energy in the form of a magnetic field. The inductor generates a magnetic field that stores energy as current passes through the wire coil. Many electronic devices use inductors for energy storage and transfer because they allow the stored energy to be released back into the circuit when the
