Inductor energy storage law

Working principles of inductors and capacitors | Electronics360

In electric motors, capacitors are often used to provide an initial burst of energy during startup, assisting in overcoming inertia. How does an inductor work? Whenever an electric current travels through an inductor, energy is stored in the form of a magnetic field. It is based on the principles of electromagnetic induction, namely Faraday''s law.

From the law of energy conservation, the maximum charge that the capacitor re-acquires is (q_0). However, as Figure (PageIndex{1c}) shows, the capacitor plates are charged opposite to what they were initially. When fully charged, the capacitor once again transfers its energy to the inductor until it is again completely discharged, as shown

In the conservation theorem, (11.2.7), we have identified the terms E P/ t and H o M / t as the rate of energy supplied per unit volume to the polarization and magnetization of the material. For a linear isotropic material, we found that these terms can be written as derivatives of energy density functions.
