This document provides an introduction to basic electronic components. It discusses two types of components - passive components (resistors, capacitors, inductors) and active components (tube devices, semiconductor devices). Resistors oppose current flow, capacitors store electrical energy, and inductors produce inductance. Semiconductor devices like chips are now replacing tube devices due to their smaller size, lower power needs, and longer life. The document provides details on interpreting color codes for resistors and markings for other components.
This presentation is for beginners of electronics. This will give you a brief about all the important basic building blocks of electronics and hence will be helpful in creating a good foundation.

The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow.[citation needed]

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

An introduction to electronic components
1. An Introduction to Electronic
Components
All electronic circuits contain few basic
components. That are three passive
components and two active
components.
3. What are Passive Components?
Resistors, capacitors and inductors are
called as passive components. These
electronics components are called passive
because they 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.
4. 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.
5. Decoding Resistor Color Bands
Color Digit value Multiplier Multiplied Out Tolerance
Black 0 100 1
Brown 1 101 10
Red 2 102 100
Orange 3 103 1,000
Yellow 4 104 10000
Green 5 105 100,000
Blue 6 106 1,000,000
Violet 7 107 10,000,000
Gray 8 108 100,000,000
White 9 109 1,000,000,000
Gold ±5%
Silver ±10%
6. The 4.7kΩ resistor has color bands
of yellow and violet to begin - which
have digit values of 4 and 7 (47). The
third band of the 4.7kΩ is red, which
indicates that the 47 should be
multiplied by 102 (or 100). 47 times
100 is 4,700!
7. Decoding Surface-Mount Markings:
In the above example picture, resistors are
marked 104, 105, 205, 751, and 754. The
resistor marked with 104 should be 100kΩ
(10x104), 105 would be 1MΩ (10x105),
and 205 is 2MΩ (20x105). 751 is 750Ω
(75x101), and 754 is 750kΩ (75x104).
8. So a 01C resistor is our good friend,
10kΩ (100x100), 01B is 1kΩ (100x10),
and 01D is 100kΩ. Those are easy,
other codes may not be. 85A from the
picture above is 750Ω (750x1)
and 30C is actually 20kΩ.
10. Letter Multiplier Letter Multiplier Letter Multiplier
Z 0.001 A 1 D 1000
Y or R 0.01 B or H 10 E 10000
X or S 0.1 C 100 F 100000
The letter at the end represents a multiplier,
matching up to something on this table:
11. Capacitors
Capacitor is a component that is used to store
electrical energy and release them whenever
desired. It is measured in Farads. Capacitors like
resistors can either be fixed or variable. Some
common capacitors are mica, ceramic, paper
and air gang capacitors.
12. Inductors
The electronic component which produces
inductance is called an inductor. The inductance
is measured in henrys (H). Also called
a coil or reactor which resists changes in electric
current passing through it.
13. What are Active Components?
Active components are used in
electronic circuits. They are classified
in two categories: Tube devices and
semiconductor devices. Due to many
advantages of semiconductor devices,
they are replacing tube devices in
many electronic applications.
14. Some Advantages of Semiconductor
Devices:
• The ability to vary the electrical properties of
semiconductors has revolutionized the design
and capabilities of modern electronics, making
devices smaller and faster.
• Chips are much smaller than vacuum tubes
and can perform many more functions while
using much less power.
• Long life
15. Some Advantages of Tubes
Devices:
• Advantage of tubes over semiconductor
components in high-power applications is
their rebuildability. When a large tube fails, it
may be disassembled and repaired at far
lower cost than the purchase price of a new
tube. When a semiconductor component fails,
large or small, there is generally no means of
repair.
16. • In the fields of high-power, high-speed circuit
switching, specialized tubes such as hydrogen
thyratrons and krytrons are able to switch far
larger amounts of current, far faster than any
semiconductor device designed to date.
• In high-power microwave transmitter
applications, the excellent thermal tolerance of
tubes alone secures their dominance over
semiconductors(allows tubes to dissipate more
thermal energy for a given amount of dissipation
area, which makes them smaller and lighter in
continuous high power applications).
17. • Tubes, being less complex in their
manufacture than semiconductor
components, are potentially cheaper to
produce as well. Semiconductor manufacture
is quite complex, involving many dangerous
chemical substances and necessitating super-
clean assembly environments. Tubes are
essentially nothing more than glass and metal,
with a vacuum seal.
