🔌 Fundamentals of Electronic Components
This paragraph introduces the basic classification of electronic components, distinguishing between passive and active components. Passive components, such as resistors, capacitors, and inductors, are essential for their non-amplifying roles in circuits. Resistors oppose current flow and are measured in ohms. Capacitors store and release electrical energy, measured in farads, and can be fixed or variable, with common types being mica, ceramic, paper, and argon. Inductors generate inductance, measured in henries, and are also available in fixed or variable configurations. Active components, which require an external energy source to control electron flow, include semiconductor devices like diodes, transistors, and integrated circuits. Diodes allow unidirectional current flow and are used in conversion circuits, with types such as PN, Zener, LEDs, and photodiodes. Transistors function as switches and amplifiers, controlled by voltage or current, and come in bipolar junction (BJT) and field-effect (FET) varieties. Integrated circuits are complex components with thousands of transistors and other elements on a silicon chip, used in modern devices like smartphones and computers, and can be analog or digital. The paragraph also briefly mentions display technologies like LCD, LED, and CRT, as well as power sources such as batteries, which convert chemical energy to electrical energy through electrochemical reactions and are categorized as primary (non-rechargeable) and secondary (rechargeable) cells.
📺 Display Technologies and Power Sources
The second paragraph delves into display technologies, highlighting the Liquid Crystal Display (LCD) technology commonly used in monitors, mobile phones, and calculators. It explains how LCDs function using polarized filters and electrodes to control light visibility to the viewer. Additionally, the Cathode Ray Tube (CRT) display technology is discussed, which is used in televisions and computer screens and operates by moving an electron beam across a phosphorescent screen within an elongated vacuum tube. The paragraph also covers the topic of batteries, detailing their role as a prevalent power source for various applications, from industrial to handheld devices. Batteries transform chemical energy into electrical energy through electrochemical reactions and consist of one or more cells, each with an anode, cathode, and electrolyte. The types of battery cells are differentiated into primary cells, which are not rechargeable, and secondary cells, which are rechargeable.

classification of electronic components
all electronic circuits contains few
basic components that are three passive
components and two active components an
integrated circuit may comprise of
thousands of transistors few capacitors
on a small chip the electronic
components are classified broadly as
passive and active components now let's
look into the passive components
resistors capacitors and inductors are
called as passive components these
electronic components are called
passive because they're by themselves
are not capable of amplifying or
processing an electrical circuit however
passive components are as important as
active components in any electronic
circuit resistors the component that
opposes the flow of current is called a
resistor this opposing force is called
the resistance of the material it is
measured in ohms capacitors capacitor is
a component that is used to store
electrical energy and release them
whenever desired it is measured in
farad's capacitors like resistors can
either be fixed or variable some common
capacitors are mica ceramic paper and
argon capacitors inductor the electronic
component which produces inductance is
called an inductor the inductance is
measured in henries all inductors like
resistors and capacitors are listed as
fixed set and variable active components
active components are used in electronic
circuits they are classified into two
categories tube devices and
semiconductor devices
due to many advantages of semiconductor
devices they are replacing tube devices
in many electronic applications these
components rely on a source of energy
and are able to control the electron
flow through them some of these
components are semiconductors like
diodes transistors integrated circuits
various displays like LCD LED CRTs and
power source like batteries and other AC
and DC supply sources diodes a diode is
a device that allows current to flow in
one direction and usually made with
semiconductor material it has two
terminals anode and cathode terminals
these are mostly used in converting
circuits like AC to DC Circuit's these
are of different types like PN diodes
Zener diodes LEDs photo diodes etc
transistors a transistor is a three
terminal semiconductor device mostly it
is used as switching device and also as
an amplifier this switching device can
be a voltage or current controlled by
controlling the voltage applied to one
terminal controls the current flow
through the other two terminals the
transistors are of two types namely
bipolar Junction transistor BJT and
field effect transistor fvt and further
these can be PNP and NPN transistors
integrated circuits an integrated
circuit is a special component which is
fabricated with thousands of transistors
resistors diodes and other electronic
component on a tiny silicon chip
these are the building blocks of current
electronic devices like cell phones
computers etc this can be analog or
digital integrated circuits mostly used
ICS in electronic circuit or opie amps
timers comparators switches ICS and so
on this can be classified as linear and
nonlinear icees depending on its
application display devices LCD a liquid
crystal display is a flat display
technology which is mostly used in
application like computer monitors cell
phone displays calculators etc this
technology uses two polarized filters
and electrodes for selectively disable
or enable the light to the eyes of the
viewer
CRT cathode ray tube display technology
is mostly used in televisions and
computer screens that works on the
movement of an electron beam back and
forth on the back of the screen this
tube is an elongated vacuum tube in
which flattened the surface has external
components as electron gun electron beam
and phosphorescent screen batteries
batteries are most common power source
for standalone industrial domestic and
handheld device applications it converts
chemical energy into electrical energy
through the electrochemical discharge
reactions these consist of one or more
cells and each cell contains an anode
cathode and electrolyte the battery
cells are classified into two types
namely primary cells and secondary cells
the primary cells are not of
rechargeable type but the secondary
cells can be rechargeable thank you
