how to judge whether the inductor and capacitor have energy storage or not

How do inductors store energy?

The energy in a capacitor can be thought as being stored in the electric field. The energy is stored in the magnetic field for an inductor which needs to have charges moving, an electric current. So if the current is reduced or eventually made zero the magnetic field would be reduced and so the energy stored in the inductor decreases. – …

Can you store energy in an inductor and use it later?

Most capacitors have an order of magnitude better energy storage (higher Q) than that. People can and do store some energy in inductors for use later. But in nearly all energy-storage situations we use something else, because that something else either (a) has lower up-front costs or (b) is more efficient or (c) requires less space or (d) …

Summary. Inductors are one of the most fundamental devices in circuits, a passive 2-terminal device that finishes the trifecta - resistor, capacitor, and inductor. They''re easy to deal with in ideal DC circuits but get more complicated as their impedance changes with frequency. And, as always, real life is always more challenging than the ...

How does an inductor store energy?

There are two ways to look at this: Circuit theory: In an inductor, a changing current creates a voltage across the inductor (V = Ldi dt). Voltage times current is power. Thus, changing an inductor current takes energy. Physics: A changing magnetic field creates an electric field.
