The energy storage process is influenced by the inductor''s inductance, current, core material, and coil geometry. Understanding how inductors store and release energy is vital for designing electronic circuits and systems that utilize inductors for filtering, power supply stabilization, and energy storage applications.
Capacitors and inductors, which are the electric and magnetic duals of each other, differ from resistors in several significant ways. • Unlike resistors, which dissipate energy, capacitors and inductors do not dissipate but store energy, which can be retrieved at a later time. They are called storage elements.
