6. Introduction
We are living in an age of Information
Technology.
Electronics is the very basic foundation of this
computer age.
6
7. Introduction
Different types of electronic equipment are
used by us in our every day life.
Devices like TV, AC and Telephone e.t.c
Electronics have made deep impact on our
every day life such as health care,
automobiles, space travels, e.t.c
7
8. History of electronics
The invention of Vacuum tube brought in the
age of electronics.
Many new and exciting applications were
found for devices.
Edison, Marconi, Ambrose, De Forest , etc
are associated with electronics.
8
9. History
After World war 2 , the transistors were
introduced instead of this.
There came the concept of IC, that stands for
Integrated Circuit.
Today IC is found in every modern electrical
device like computers, cars, TV, CD players,
cell phones, etc.
9
12. Pre-requsite
To have a basic knowledge of principles of
electricity and magnetism.
There comes an assignment with it , whose
details will be told by me in last.

14. Resistors
A resistor is an electrical component that
limits or regulates the flow of electrical current
in an electronic circuit.
Resistors can also be used to provide a
specific voltage for an active device such as a
transistor.
14
15. Resistivity
The electrical Resistance of an electrical or electronic
component or device is generally defined as being the
ratio of the voltage difference across it to the current
flowing through it, basic Ohm´s Law principals.
The problem with using resistance as a measurement
is that it depends very much on the physical size of the
material being measured as well as the material out of
which it is made.
For example, if we were to increase the length of the
material (making it longer) its resistance would also
increase proportionally.
15
16. Transistors
A transistor is a device that regulates current
or voltage flow and acts as a switch or gate
for electronic signals.
Transistors consist of three layers of a
semiconductor material, each capable of
carrying a current.
16
17. Capacitors
A device used to store an electric charge,
consisting of one or more pairs of conductors
separated by an insulator.
17
18. Diodes
A diode is a specialized electronic component
with two electrodes called the anode and
the cathode. Most diodes are made
with semiconductor materials such as silicon,
germanium, or selenium.
18
19. Inductor
An inductor is an electronic component that
stores energy in the form of a magnetic field.
In its simplest form, an inductor consists of a
wire loop or coil.
19
20. Conductor
A conductor is an object or type of material
that allows the flow of an electrical current in
one or more directions.
Copper, human body, water,etc
20
21. Semi-conductor
A semiconductor is a material whose electrical
conductivity is between that of a conductor
and an insulator.
The elements most commonly used in
semiconducting devices
are silicon and germanium.
21
22. Insulator
Insulators are used to protect us from the
dangerous effects of electricity flowing
through conductors.
Glass, plastic, rubber, air and wood
22
23. Intrinsic semi-conductor
An intrinsic semiconductor is an un-doped
semiconductor.
This means that holes in the valence band
are vacancies created by electrons that have
been thermally excited to the conduction
band.
As opposed to doped semiconductors where
holes or electrons are supplied by a “foreign”
atom acting as an impurity
23
25. Extrinsic semi-conductor
An extrinsic semiconductor is a
semiconductor doped by a specific impurity
which is able to deeply modify its electrical
properties.
Making it suitable for electronic applications
(diodes, transistors, etc.) or optoelectronic
applications (light emitters and detectors).
25
27. Band theory
Band theory, in solid-state physics,
theoretical model describing the states
of electrons, in solid materials, that can have
values of energy only within certain specific
ranges.
The behavior of an electron in a solid is
related to the behavior of all other particles
around it.
27
29. PN junction
A p–n junction is a boundary or interface
between two types of semiconductor
materials, p-type and n-type, inside a
single crystal of semiconductor.
The "p" (positive) side contains an excess
of holes, while the "n" (negative) side contains
an excess of electrons in the outer shells of
the electrically neutral atoms there
29
30. PN junction
p–n junctions are used as the elementary "building
blocks" -- diodes and transistors -- in
most semiconductor electronic
devicesincluding integrated circuits.
They are the active sites where the electronic action of
the device takes place. For example, a common type
of transistor, the bipolar junction transistor, consists of
two p–n junctions in series, in the form n–p–n or p–n–p.
They are also used in solar cells and LEDs. A Schottky
junction is a special case of a p–n junction, where
metal serves the role of the p-type semiconductor.

33. Assignment
In next class you will submit a hand- written
assignment that will be about electricity and
magnetism principles.
Copied assignments won’t get any assistance
in terms of marks.
