At large values, it keeps on going, despite the low inductance, because current is just so high up there. Finally, to address the question: Energy storage will always be increasing; at least, as long as there isn''t any mechanical movement to sap energy from the system. The quadratic term must dominate, in the end. The real question is this:

6 FAQs about [Long-term energy storage in inductance]

What factors affect the energy storage capacity of an inductor?

The energy storage capacity of an inductor is influenced by several factors. Primarily, the inductance is directly proportional to the energy stored; a higher inductance means a greater capacity for energy storage. The current is equally significant, with the energy stored increasing with the square of the current.

How do inductors store energy?

In conclusion, inductors store energy in their magnetic fields, with the amount of energy dependent on the inductance and the square of the current flowing through them. The formula \ ( W = \frac {1} {2} L I^ {2} \) encapsulates this dependency, highlighting the substantial influence of current on energy storage.

How does Linear Technology affect inductor energy storage?

While one inductor’s current is increasing, the other’s is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor’s volume, and therefore cost, are reduced as well. See Linear Technology’s Application Note 77 for complete details.

What is the theoretical basis for energy storage in inductors?

The theoretical basis for energy storage in inductors is founded on the principles of electromagnetism, particularly Faraday's law of electromagnetic induction, which states that a changing magnetic field induces an electromotive force (EMF) in a nearby conductor.

How do you find the energy stored in an inductor?

The energy, stored within this magnetic field, is released back into the circuit when the current ceases. The energy stored in an inductor can be quantified by the formula \ ( W = \frac {1} {2} L I^ {2} \), where \ ( W \) is the energy in joules, \ ( L \) is the inductance in henries, and \ ( I \) is the current in amperes.

Why is inductance important?

The inductance (\ ( L \)) of an inductor, a measure of its ability to store energy in a magnetic field, is a fundamental property that determines how much opposition the inductor presents to changes in current, thus affecting the induced voltage.
