- a person who inducts
- Chem. a substance that speeds up a slow chemical reaction
- Elec. a device designed primarily to introduce inductance into an electric circuit
Origin of inductorClassical Latin one who stirs up, literally , one who leads or brings in
inductor - Computer Definition
A device comprising one or more windings of a conductive material, around a core of air or a ferromagnetic material, for introducing inductance into an electric circuit.An inductor opposes changes in current, whereas a capacitor opposes changes in voltage. See also capacitor, inductance, and inductive reactance.
A coil of wire that generates a magnetic field when current is passed through it. The strength of the magnetic field is measured in henrys (H). When the current is removed, as the magnetic field disintegrates, it "induces" a brief current in the opposite direction of the original. Thus "induction" is caused by the opening and closing of a DC circuit or the continuous changing of directions in an AC circuit. High-Frequency Filters An induction coil impedes the flow of high-frequencies in an AC circuit, which is why inductors are used as surge protectors, choking off any high-frequency shifts. The tiny donuts placed on the end of signal cables and the load coils placed into telephone networks are examples. See induction.
