What is the formula of energy stored in inductor?

In Physics, especially in the study of electromagnetism, it's of utmost importance to comprehend the fundamental formula of energy stored in inductor. This formula is represented as: W = 1 2 L I 2 In this equation, W represents the energy stored in the inductor, L is the inductance, and I is the current.

How is energy stored in an inductor?

Energy in the inductor is stored in the form of a magnetic field. When current is applied, the energy of the magnetic field expands and increases the energy stored in the inductor. The energy remains constant as long as the current is maintained. If the current is removed, the energy is discharged as the magnetic field contracts.

How are energy storage mechanisms represented in electric circuits?

These two distinct energy storage mechanisms are represented in electric circuits by two ideal circuit elements: the ideal capacitor and the ideal inductor, which approximate the behavior of actual discrete capacitors and inductors. They also approximate the bulk properties of capacitance and inductance that are present in any physical system.

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 does inductance affect energy stored in an inductor?

Inductance of the coil: The amount of energy stored in an inductor is directly proportional to its inductance. Higher the inductance, higher will be the energy stored. Current flowing through the coil: The energy stored is directly proportional to the square of the current flowing through the inductor.
