Question

Being reactive elements, inductors store energy rather than dissipate it. Discuss applications of inductors in modern electronic systems and describe how the storage of energy plays a role in these applications.

Answer 1

Inductor is a coil of a wire which ia used generate magnetic Flux and stores electrical energy in the form of magnetic flux when alternating current ia passed through it.

Application of inductor

use of inductor in a tunning circuit

Inductors are used in tuning circuits to select the desired frequency so that we can access our desired channel

Inductors are used in the smps (Switching mode power supply) which we use generly for the supply of our computer in smps it works as electrcal energy storage device.

inductors are used in a proximity sensors.

inductors are used in a Induction motors. In these induction motors or asynchronous motors, the inductors are in fixed position and they did not allowed to move in nearby magnetic field.Induction motors converts the electrical energy into mechanical energy. The shaft in the motors will rotate because of the magnetic field produced by the alternating current.

Inductors are used in a transformer. These are used to incr or decthe power in transmission lines to required level, as step up and step down transformers respectively. In the transformers, the inductor is wounded to the core as primary and secondary windings

inductors are used in low pass, high pass, band pass, bandstop and many more filters.

Inductors are also used as chokes. We know that the inductors will create an opposite current flow, when the alternating current flows through it. This means the inductors will choke the AC current and allows DC current to pass. This property of inductors is used in power supply circuits, where AC supply need to be converted to DC supply.
