What is the purpose of a coil inductor?
While simple in concept, an inductor coil does sophisticated things with electricity and magnetism, either amplifying or reducing signals of different frequencies. You’ll find inductors in radio and television circuits, as well as in tranformers and many other electrical components.DescriptionAn inductor is simply a coil of insulated wire. The strength of its inductance depends on several factors, including how many turns of wire are in the coil, and whether the coil surrounds an iron core.FilterSimple circuits made of an inductor, capacitor and resistor can enhance a particular signal frequency. For example, a radio uses this circuit to tune in different stations. An inductor on its own can filter out frequencies that are higher or lower than the one it’s tuned to.TransformerTwo inductors, placed closely together, make up a transformer. A transformer can isolate unwanted direct current (DC) signals, or increase or decrease the voltage in an alternating current (AC) signal. Transformer
