Energy Stored In An Inductor

The current flowing through the inductor generates the magnetic field where the energy is actually stored. The work done is equal to the potential energy stored in the inductor.

Solved Problem 1 Show That For The Circuit Shown Below T

In a pure inductor the energy is stored without loss and is returned to the rest of the circuit when the current through the inductor is ramped down and its associated magnetic field collapses.

Energy stored in an inductor. The energy stored in the magnetic field of an inductor can be written as. W 1 2 l i 2 1 where. W 1 2li2 2 w 1 2 l i 2 2 where w is the stored energy in joules l is the inductance in henrys and i is the current in amperes.

An inductor also called a coil choke or reactor is a passive two terminal electrical component that stores energy in a magnetic field when electric current flows through it. The energy stored in an inductor with inductance 10 h with current 5 a can be calculated as. Consider a simple solenoid.

An inductor typically consists of an insulated wire wound into a coil around a core. The inductor absorb power is. Energy stored in the inductor is the multiplication of current through inductor and voltage across it.

The inductor works like a capacitor and doesn t dissipate energy. W 1 2 10 h 5 a 2. W energy stored joules j l inductance henrys h i current amps a example energy stored in an inductor.

It stores electric energy in the form of the magnetic field during the charging phase and releases the same energy to the circuit in the decay phase. The potential energy in a capacitor is stored in the form of electric field and the kinetic energy in an inductor is stored in the form of magnetic field. Energy stored in inductor establishing a current in the inductor requires work.

In a pure inductor the energy is stored without loss and is returned to the rest of the circuit when the current through the inductor is ramped down and its associated magnetic field collapses. The energy stored in the magnetic field of an inductor can be calculated as. This energy is actually stored in the magnetic field generated by the current flowing through the inductor.

A user enters the inductance l and the current i and the result will automatically be calculated and shown. The inductor energy calculator calculates the energy stored in an inductor based on the size of the inductance of the inductor and the current going through it according to the above formula. In summary inductor acts as inertia which reacts against the change in velocity of electrons and capacitor acts as spring which reacts against the applied force.
