2. What is Electronics?
 Electronics is the science of how to control electric energy,
energy which the electrons have a fundamental role.
 Its also deals with electrical circuits that involve active electrical
components such as vacuum tubes, transistors, diodes and
integrated circuits, and associated passive electrical
components and interconnection technologies.
 You will work with a number of basic electronic components
when building electronic circuits, including resistors,
capacitors, diodes, transistors, and integrated circuits. Here is
a brief overview of the functions of each of these basic
electronic components.

3. Part of Electronics Components
 Transformer (Trafo)
 Integrated Circuits (IC)
 Multimeter/Ohmmeter
 Capacitor
 Resistor
 Diode
 Light-Emitting Diodes (LED)
 Transistors

4. Transformer (Trafo)
 A transformer is an electrical device that transfers electrical
energy two or more circuits through electromagnetic induction.
 Commonly, transformers are used to increased or decrease the
voltages of alternating current in electric power.
 Transformers can thus be designed to efficiently change AC
voltage from one voltage level to another within power
networks. Transformers also can be used in television,
computer, and electric station.

5. Integrated Circuits
 Integrated circuit, another name for a chip, is a small electronic
device made out of semiconductor material.
 The first IC was developed in the 1950s by Jack of Texas
Instruments and Robert Noyce of Fairchild Semiconductor.
 ICs are used for a variety of devices, including
microprocessors, audio and video equipment, automobiles,
and other home appliances.

6. Multimeter/Ohmmeter
 A multimeter, also known as a Volt-Ohm meter, is an electronic
measuring instrument that combines several measurement
functions in one unit.

7. Capacitor
 Capacitor is a passive two-terminal electrical component used
to store electrical energy temporarily in an electric field.
 Capacitors come in several different varieties, the two most
common being ceramic disk and electrolytic. The amount of
capacitance of a given capacitor is usually measured in
microfarads, abbreviated μF.

8. Resistors
 Resistor is passive-two
electrical component that
implements electrical
resistance as a circuit
element. Resistors act to
reduce current flow, and,
at the same time, act
lower voltage levels within
circuits.
 If you put resistors next to
a penny, you get an idea
of how small they are.

9. Diode
 Diode is a two-terminal electronic component with asymmetric
conductance; it has low resistance to current in one direction,
and high resistance in the other.
 The most common function of a diode is to allow an electric
current to past in one direction, while blocking current in the
opposite direction.

10. Light-Emitting Diodes
 A light-emitting diode (or LED) is a
special type of diode that emits light
when current passes through it.

11. Transistor
 Transistor is a semiconductor device used to amplify and
switch electronic signals and electrical power. It is composed of
semiconductor material with at least three terminals for
connection to an external circuit.
