INDUCTORS
Lenz's law
Straight wire conductor
it is a passive two terminal electronic component that temporarily stores the electrical energy in the form of a magnetic field. It consists of coil of copper wires or electrical conductive wires.
the unit of inductance is the henry (H)
Q factor
An inductor is also called a coil, choke or a reactor,
They are also used in electronic filters to separate signals of different frequencies, and in combination with capacitors to make tuned circuits, used to tune radio and TV receivers.
Energy stored in an inductor
direction of the electric current which is induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial changing magnetic field
Ideal and real inductors
TYPES
Air-core inductor
Radio-frequency inductor
Ferromagnetic-core inductor
Ferrite-core inductor
Laminated-core inductor
Toroidal-core inductor
Powdered-iron-core inductor
Choke
Variable inductor
Inductors in a parallel configuration each have the same potential difference (voltage)
The current through inductors in series stays the same, but the voltage across each inductor can be different
Cylindrical air-core coil
APPLICATIONS
Induction Motors
The well known and wide range application of inductors is Induction motors
Transformers
Transformer is another popular application of inductors. By combining the inductors of shared magnetic field, we can design a transformer
Energy Storage Devices
We can store the energy in passive elements like capacitor and inductors. Inductors can store energy for a limited time
Inductive Filters
Inductors and capacitors are combinely used to form filters
Inductive sensors
Inductors are used in proximity sensors which work on the principle of inductance
Chokes
Inductors are also used as chokes
Inductors in Tuned Circuits
Inductors are used in tuning circuits which are used to select the desired frequency
