2.
Electronics is thebranch of science and
engineering those designs, constructs, and
operates devices and systems that use
electric currents or electromagnetic fields.
Electronics has applications in many fields,
such as :
communication
computing
medicine
entertainment
and industry
4.
Electricity is theflow of electric charge
through a conductor.
It is one of the most important forms of
energy in modern society, powering
homes, industries, and transportation.
Electricity can be generated from various
sources, such as fossil fuels, nuclear
power, renewable energy, and batteries.
5.
Here are someof the basic electrical
symbols and components.
6.
Auto electrical isa specialized field of automotive
service that involves the diagnosis, repair and
installation of electrical components and systems
in vehicles.
Auto electricians work with batteries, alternators,
starters, wiring, lighting, sensors, computers and
other electronic devices that are essential for the
proper functioning of modern cars.
Auto electricians need to have technical skills and
familiarization of the different auto electrical
symbols. Here are some of them.

TYPES OF CIRCUITDIAGRAMS
Circuit diagrams are graphical
representations of electrical circuits
that use symbols to show the
components and connections. Circuit
diagrams can design, test, and
troubleshoot electrical circuits and
communicate a circuit's logic and
functionality.
10.
The following arethe different types of circuit
diagrams
1. Block Diagram- it represents
the main components of a complex
system using blocks interconnected
by lines. It highlights the function
of each component and the flow
process.
12.
2. Schematic Diagram-depicts electrical components using standardized
symbols. It shows connections, switches, resistors, and other
components.
13.
3. Pictorial Diagram-uses simple images of components. It provides a visual
representation of the circuit. It is less detailed than schematic diagrams.
14.
4. Single LineDiagram (One-Line
Diagram)- represents an entire
electrical system using a single
line. This type of diagram is
usually used in power distribution
systems. Single line diagram
simplifies complex networks for
better understanding.
