REACTANCE COIL Meaning and
Definition
-
A reactance coil, also known as a choke coil or simply a reactor, is an electrical component that is primarily used to limit or control the flow of alternating current (AC) while allowing direct current (DC) to pass through without any impedance. It is essentially an inductor specifically designed to produce a large inductive reactance, and hence opposition, to the flow of AC current.
The reactance coil consists of a wound coil of wire with a magnetic core, typically made of iron or ferrite material. The number of turns in the coil and the properties of the core determine the value of inductive reactance produced by the coil.
When an AC voltage is applied across a reactance coil, it induces an electromagnetic field that opposes the change in current flow. This opposition to AC current is called inductive reactance, which increases with the frequency of the AC voltage. As a result, the reactance coil effectively limits the flow of AC current while allowing DC to pass through without any significant impedance.
Reactance coils are commonly used in various electrical applications, including power supplies, electrical filters, electronic ballasts, motor control circuits, and impedance-matching networks. They are particularly useful for smoothing out ripple voltage in power supplies and reducing electromagnetic interference in circuits.

Etymology of REACTANCE COIL
The word "reactance coil" is a compound term consisting of two components: "reactance" and "coil".
The term "reactance" refers to the opposition that an electrical circuit offers to the flow of alternating current (AC), caused by inductance or capacitance in the circuit. It can be thought of as a measure of the circuit's ability to store or release energy in response to changes in current or voltage.
The word "coil" typically refers to a wound or spiral-shaped structure, often made of wire. In the context of electrical engineering, a coil usually refers to an inductor—a passive electronic component that stores energy in a magnetic field when current flows through it.
