3. ELECTRONICS
 The branch of science/physics which deals with the
study of electricity and electrical devices is called
Electronics.
 The branch of science/physics which deals with the
transistors ,capacitors , conductors and insulators
etc.
 In which we study about the controlling of electric
currents. (i.e to stop, to flow, to maximize or to
minimize a current).
 In which we deals about the electric circuits.
 In which we study about the flow of electrons.

4. ELECTRONICS
 The electronics deals with the Diodes, PN Junction,
Rectifier, Bridge Rectifier, accumulator and AC and
DC circuits.
 The field of electronics was invented in 1883.

5. ELECTRICITY
 Electricity is the flow of electrons in a specific media
is known as Electricity.
 The electricity flows through atoms . Atoms is every
material which is made up of electrons, proton and
neutron.
 The electron and proton hold the atoms together. i.e
positive and negative charge hold the atom.

7. CONDUCTORS
 The device/material used for moving/flowing of
electrons is known as conductor.
 In conductors the electron freely move from one
atom to another.
 We can also call that those device/material in which
electricity /electric current pass through it is called
conductor.
 EXAMPLES:
 Copper, silver, gold etc.

CONDUCTORS

9. SEMI-CONDUCTOR
 A device/material which having dual functionality is
called semi-conductor.
 A semi conductor is a device which having quality
of both conductors and insulators.
 A semi-conductor can conduct/pass less than
conductor and more than that of insulators.
 A semi-conductor devices are basically used for
transiting /resistance.

10. SEMI-CONDUCTOR
 The semi-conductor have four electrons in outer
orbit. Two electrons used for less conducting and
two are used for insulating.
 EXAMPLES:
 Carbon (C ): Carbon is a good semi-conductor.
 Germanium (G): Germanium is also semi-
conductor.
 Silicon (Si): Physically all transistor are made of
silicon and silicon is a semi conductor.

11. TYPES OF SEMI-CONDUCTOR
 There are two types of semi-conductors:
 1)INTRINSIC Semi-conductor:
 A semi-conductor
used for conducting/flowing of electricity, heat and
sounds is known as intrinsic semi-conductor.
 2)EXTRENSIC Semi-conductor:
 A semi-conductor
device used for insulating/resisting of electricity,
Heat and sound is known as extrinsic semi-
conductor.

13. INSULATOR
 A device/material which can not allow free
movement of electrons is called Insulators.
 The electric current/electricity can not pass through
it.
 In insulators there are electrons but only stay in
orbits and can not move freely.
 An insulators can hold or store electricity but can
not conduct/pass electric current /electricity.

14. INSULATOR
 Insulator is used for stopping/prevent of electric
current/electricity.
 Capacitor is an insulator.
 Capacitor: Capacitor is a device which store
electric charge and good insulators. Capacitor is
used for breakdown of current and voltage.
 EXAMPLES:
 Rubber, Glass ,Plastic, Paper and Air etc.
