Inductor Working And How To Use In Practical Circuits
We suggest you to read this inductor working and applications tutorial twice to establish a strong understanding about inductors.
Practical uses for inductors. The input signals frequency while entering the circuit is limited with the use of these filters. Important applications of inductors are in rf transmitters receivers power supplies signal filters and so on. Inductors are used extensively with capacitors and resistors to create filters for analog circuits and in signal processing.
When the current flowing through an inductor changes the time varying magnetic field induces an electromotive force emf in the. Like resistors and capacitors inductors are also passive elements which are used to store the electric energy in the form of magnetic field. The right hand curl rule for a solenoid.
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. September 5 2015 by administrator leave a comment. Alone an inductor functions as a low pass filter since the impedance of an inductor increases as the frequency of a signal increases.
Many practical inductors are based on the solenoid. Thats pretty much about inductors and its applications in practical circuits. With the increase in the frequency of supply the inductors impedance increases.
Inductors are extensively used in alternating current ac applications such as radio tv and communications equipment and in these systems how inductors react to ac signals of different frequencies is very useful. Another name used for an inductor is a choke. Inductors made of superconducting wire zero resistance are more practical to build and safely operate than capacitors of equivalent value and are probably smaller too.
Inductors when combined with capacitors will be used as filters. An inductor typically consists of an insulated wire wound into a coil around a core. Simply an inductor is a wire or coil of a good electric conducting material with few turns twists in it.
A notable exception to this rule is in applications requiring huge amounts of either capacitance or inductance to store electrical energy. Because of its shape the lines of magnetic flux are concentrated along the centre line of the coil and this produces a magnetic field with a north and a south pole.
