Abstract

There are different type of electronic diagrams including, a functional block, single

line, schematic, connection or wiring, and interconnection diagram. Three of the

most common diagrams are the schematic, single line and functional block diagram.

All diagrams have symbols that represent components of a circuit such as a resistor,

capacitor, voltage, inductor, and switch. Also, all diagrams represent the information

needed to construct a circuit and to identify and problems in the circuit.

circuit. The purpose of a circuit diagram is to show all the connection of a circuit and

understand how each connection works. The diagram is useful when testing, designing,

constructing and maintaining the circuit or system. There are different types of diagrams;

functional block diagram, schematic diagram, single line diagram, wiring diagram and

interconnection diagram. In most types of diagrams symbols are used to represent

elements in the circuit such a resistors, capacitors, anodes, inductors, voltages, etc. Three

useful diagrams that are common in the electrical engineering industry are schematic,

single line and functional block diagrams.

A schematic diagram represents elements of a circuit graphically. These types of

diagrams are use to layout a clear representation of a circuit to display information, also

to better understand how each component is connected. Nevertheless, the ways these

schematic diagrams are drawn are not going to look similar to the circuit constructed. The

purpose of a schematic diagram is to understand how the circuit works and to easily

construct a circuit. To draw a proper schematic diagram each component used must have

a proper value to derive the output.

A single line diagram is a representation of a power system by using the necessary

elements. The purpose of the single line diagram is to represent a network that shows the

main connections along with element such as resistors, voltage, resistance, output, etc.

Single line diagrams are drawn in the form of each symbol used, for instance

transformers, delta, and star are drawn on the side along the line.

A block diagram is different than a schematic and single line diagram. It provides

a view of the systems to be able to identify a point of interest or to identify any trouble
spots. This diagram does not have detailed information to be able to implement a circuit.

They are made of shapes like a square and circle with information on each block. The

main purpose of block diagrams is to focus on the input and output of a system. In other

words, block diagrams do not have any wiring connection to any components.

After designing a circuit in a schematic diagram or in a single line diagram it is

ready to be constructed in a printed circuit. Printed circuits is an electrical device in

which each component and wire is a thin coat of electrically conductive material. They

reduce the size and weight of all of the equipment and improve the reliability of the

circuits. There are different types of printed circuits like a multilayered and a double

sided. These circuits are used for many electronics such as a radio, television, computes,

etc.
CAD drawing of some Symbols

The following symbols are used to construct a circuit diagram.

Conclusion

The symbols demonstrated above are a very important component to design a

circuit diagram. Each component has different functions and should be set to the

proper values to derive the right output. Schematic diagrams are very informal and

are used to understand how each circuit works and where each element is

connected. These diagrams make it less complicated to construct a circuit.

Furthermore, a single line diagram is used for power systems and are design to

create a network that shows the main connection of a system and it also includes

resistors, transformers, inductors etc. And a function block diagram does not
include any of the following symbols mentioned. The purpose of these diagrams is to

focus on the input and output. Therefore these diagrams include shapes like circles

and squares with labels inside them. In conclusion the circuit diagrams are very

useful in the electric industry and help understand how each system works.
