An inductor is a passive electronic components that stores energy in the form of a magnetic field. An inductor consists of a wire loop or coil. The inductance also directly on the radius of the coil and on the type of material around which the coil is wound.
henry is the Standard unit of Inductance, abbreviated H. This is a large unit. More common units are the microhenry, abbreviated and the millihenry abbreviated. Occasionally, the nanohenry it is difficult to fabricate inductors onto intergated circuit(IC) chips. Fortunately, resistors can be substitued for inductors in most microcircuit applications. in some cases inductance can be simulated by simple electronic circuit using transistor, resistor and capacitors fabricated onto IC chips.
Inductor are used with capacitors in various wireless communications applications. An inductor connected in series or parellel with a capacitor can provide discrimination against unwanted signals. Large inductors are used in the power supplies of electronic equipment of all types, including computers and their peripherals. In these system the inductors help to smooth out rectified utility Ac providing pure, battery like DC.
