Constitutive equation [edit] Any change in the current through an inductor creates a changing flux, inducing a voltage across the inductor. By Faraday's law of induction, the voltage...
In this tutorial we will see that the inductor is an electrical component used to introduce inductance into a circuit which opposes the change of current flow, both magnitude and direction, and that even a straight piece of conductive wire can have some amount of inductance in it. In our tutorials about Electromagnetism we saw that when an electrical current flows through a wire conductor, a magnetic flux is developed around that conductor. This affect produces a relationship between the direction of the magnetic flux, which is circulating arou ...
the current through it. If an inductor is connected across a charged capacitor, the voltage across the capacitor will drive a current through the inductor, building up a magnetic field...
As the evolution of the current through an inductor is related to the voltage across it: it can be seen that the average value of the inductor voltages over a commutation period have to be...
Inductors are used to store energy in the form of magnetic field when an electric current is passed through it. This article will cover inductors, its types, its functions and the difference betwee...
Inductive coils and solenoids are not purely inductive devices, but instead consist of an inductance and resistance connected together to form a basic LR series circuit. In the first tutorial in this section about Inductors, we looked briefly at the time constant of an inductor stating that the current flowing through an inductor could not change instantaneously, but would increase at a constant rate determined by the self-induced back-emf within the inductive coil. In other words, an inductor in an electrical circuit opposes the flow of curren ...

An inductor-type current-mode DC-DC buck converter was evaluated through HSPICE simulation with 0.18㎛ CMOS process parameters. The current programmed mode (CPM)
The peak current to and from an inductor is IL when the emf source has a peak voltage V and frequency f. What is the peak current to and from the inductor if the frequency and peak voltage are doub...
