What Is The Ideal Inductor

- March 16, 2019

An inductor is a passive electronic component that storesenergy in the form of a magnetic field. 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.

An inductor typically consists of an insulated wire wound into a coil around a core.

What is the ideal inductor. Note that this implies that the voltage across the device is zero when there is a steady constant current thus it would necessarily be the case that such a device would have zero resistance ie. The non ideal inductor is characterized by functions describing its inductance flux or flux density. If it were not zero average volts for an inductor it would take infinite amps.

Inductance also depends on the radius of the coil and on the type of material around which the coil is wound. When you apply a current through the inductor a magnetic field is created around it. The inductance is directly proportional to the number ofturns in the coil.

Non ideal inductor this component models an inductor with optional non ideal characteristics. In my introductory circuits classes i learned that inductors were lossless energy storage circuit elements that obey these current voltage rules. If it were not zero average current for a capacitor it would charge to infinite volts.

By using a magnetic core the magnetic field will be much much much stronger. Vl didt i1l vdt. Select one of the described core model types from the components properties dialog box value tab.

A perfect inductor or ideal inductor would be a two terminal device with the following voltage current relationship. Consequently energy stored at one instant in time can be retained in the core until its needed later. However real inductors will always have some resistance associated with the windings of the coil and whenever current flows through a resistance energy is lost in the form of heat due to ohms law.

An inductor is a coil wire often wound around a magnetic material such as powdered iron or ferrite. An ideal inductor is classed as loss less meaning that it can store energy indefinitely as no energy is lost. In its simplest form an inductor consistsof a wire loop or coil.

The core could be just air or it could be a magnet. That magnetic energy is stored in the inductors magnetic field. The average voltage across an ideal inductor is zero just as the average current into an ideal capacitor is always zero.

An inductor is just a coil of wire around some kind of core. An inductor transforms electrical energy into magnetic energy.
