can anyone explain the bahaviour of an inductor?

Question

and what are the possible components.

Answer 1

An electrical inductor is a component that, typcially, has a wound coil of wire and an iron core. When the electricity is first turned on in any wire, an electrical field is created. If you want a strong electric field you can use a coil where you have lots of wires in a small space. An electric field creates a magnetic field. The use of an iron core concentrates the magnetic feild, creating an electro magnet. When the electricity is turned off, there is stored energy in the magnetic field. The collapsing magnetic field creates its own electrical current in the wire of the coil. On a more basic level, a changing magnetic feild will induce an electrical feild (and therefore an electric current) in anything that conducts electricity that is close enough to "feel" the changing feild.

For the electrical behavior of LC circuits, inductance/capacitance circuits, look up info on electrical engineering. good luck

Answer 2

An inductor is a component that is made from a coil of wire. If a DC current is applied to it, it will pass straight through, since it's just a bunch of wire. However, when the current passes through the wire, it will create a magnetic field around the wire. This will not do anything to a DC current, but if it's an AC current, where the curernt direction is changing and the amount of current rises and falls with the voltage, that magnetic field will also expand and contract. If the wire was straight, this would have no effect, but since it's coiled, the magnetic field caused by the current flow will pass through other coils of wire in that same inductor.

Remember that a current flowing through a wire creates a magnetic field? The reverse is also true - a magnetic field crossing a wire will create a current flow, just like in a generator. As the AC current rises and falls in the inductor, the magnetic field expands and contracts, crossing the wires of the inductor, and creating its own currents, which interfere with the input current, which creates resistance to that AC current.

The end result is this - a DC current passes through an inductor with no resistance, but an AC current passing through causes resistance. Because the resistance is only for AC, it isn't measured in Ohms, it's measured in Henries.

Answer 3

just basicly, an inductor is a passive electronic component that stores energy as a magnetic field. In it's simplest form an inductor is made up of a coil of wire. The inductance measured in henrys, is proportional to the number of turns of wire, the wire loop diameter and the material or core the wire is wound around..

Answer 4

An inductor is just coiled wire around a core of soft iron or just air.
It produces a magnetic field when an electric current runs in the wire. The magnetic field has a steady polarity with dc current or an alternating polarity with ac current. It will be much stronger with a ferrous core.

Answer 5

ELI the ICE man

"E" (voltage) leads "I" (current) through "L" (Inductor)

"I" (current) leads "E" (voltage) though "C" (capacitor)
