3. WHAT IS AN INDUCTOR?
A passive electronic component
that stores energy in the form of a
magnetic field.
Consists of a wire loop or coil.

4. INDUCTOR formula
Where
L= inductance in Henry
di/dt = rate of change of current.

5. Capacitors Symbol
Parts

6. Capacitors Unit
Henry(H).
TYPES
1. Fixed inductors
2.Variable inductors.

7. Fixed inductor.
An inductor whose coils are wound in such a manner that the
turns remain fixed in position with respect to each other, and which
either has no magnetic core or has a core whose air gap and position
within the coil are fixed.
Variable inductors.
An inductor or reactor whose inductance is
continuously adjustable is called Variable inductors.

9. FUNCTION OF AN INDUCTOR:
Used to store such amount of current
which is flowing in the circuit & later
releases the electrical energy to the
circuit when the source of power
is removed.

10. INDUCTORS WORK:
As the electric current produces a
concentrated magnetic field around
the coil, this field flux equates to a storage
of energy representing the kinetic motion
of the electrons through the coil. The more
current in the coil, the stronger the magnetic
field will be, and the more energy the
inductor will store.

11. • FACTORS THAT AFFECT INDUCTANCE OF A COIL.
• Number of turns in the coil
• Permeability of the core material.
• Size of core.

12. • Permeability
The measure of the ability of a material to support the
formation of a magnetic field within itself.

13. • FERRO MAGNETIC MATERIAL
An inductor consist of copper wire
wound around a core made up of a
ferromagnetic material.
