What are the Basic Electronic Components and their Symbols?

If you want to gain a basic understanding of Electronic Components and Their Symbols then you have come across the right blog. Learning about electrical components appears to be a tiresome task to most people, but it helps to develop a keen understanding of electrical systems.

In this guide, we are going to break down electronic components and their symbols in a simple way.

ELEVATE YOUR KNOWLEDGE ABOUT BASIC ELECTRICAL COMPONENTS AND LEARN ABOUT THEIR SYMBOLS AS IT WILL NOT ONLY INCREASE YOUR KNOWLEDGE BUT ALSO UPLIFT TECHNICAL CAPABILITIES. 

Why is it Important to Learn About Electronic Components and Their Symbols?

Everyone who is associated with the electrical field needs to learn about electronic components. These components are designated by specific symbols that are universal.

You may ask yourself why there is a need for signs and symbols. Well, the use of symbols has made things more efficient. It increases communication and improves collaboration among workers.

Electrical Engineers or vendors need to develop an intimate knowledge of these parts.

Residential or Commercial Electrical Estimators learn about electrical equipment to create accurate cost predictions for construction projects.

Electricians need a deep understanding of electronics to deal with electrical installations, repairs or upgrades.

Mechanical or plumbing engineers also study electrical parts as these three disciplines are interlinked with one another.

It is helpful to homeowners to learn about electrical systems to make good choices. 

Types of Electronic Components and Their Symbols 

Let’s take a look at some of the most common types of electronic components and their symbols. They are divided into 5 categories. 

1) Passive Components

Passive Components do not generate any electrical power themselves but their function is to store and release power on demand, as per requirement. Passive components include 

• Resistors

It is an electronic component that restricts or allows a certain flow of current in a circuit. The symbol of the resistor is R. 

• Capacitors

A capacitor in an electronic circuit contains two terminals that are used to store energy in the form of electrical charge.

In a circuit, it is represented as two parallel diagrams which indicate its symbol.

• Inductors 

An inductor stores energy temporarily in a magnetic field when current flows through it.

The standard electrical symbol for Inductors is L.

• Transformers 

It is a device that is used to transfer electrical energy from an alternating circuit to one or multiple other circuits.

Its symbol comprises two coils which are placed next to each other.

2) Active Components

It is a semiconducting device that encompasses semiconductor materials. Their role is to provide electrical power to a particular Circuit. The most common electronic active components are as follows:

• Integrated Circuits

It is an electronic device that comprises many components. It performs various functions such as processing or storing of information. Its symbol is a rectangular box inserted with several pins.

• Diodes

It is an Electrical component in a circuit which only allows the flow of current in only one direction. In a diagram, its symbol is a triangle with a line passing through one vertex.

• Transistors

This component is made up of three components in a circuit which are its terminals and they are emitter, base and collector. A controlled electrical signal is applied to the base and it flows between the emitter and collector. It typically acts as a switch. Its symbol is an inward arrow at the base.

• Generators 

It is a device that is widely used as it converts mechanical energy into electrical energy. Its symbol is a circle containing a rotor.

3) Electromechanical Components 

Electromechanical components are those parts that are a part of both electrical and mechanical systems. 

• Motors 

A motor is responsible for converting electrical energy into mechanical energy. It can alternate both direct and alternating current.

The general symbol of an electrical motor is the symbol M inside a circle.

• Relays

Relays function as control devices. They regulate the intensity of high-voltage current by using low-power signals. It’s vital for the safety of the electrical system. When a relay contact is open, the symbol is (NO). On the other hand, when the relay contact is closed the symbol is (NC).

4) Switches and Connectors

Switches and connectors are two of the most important parts of the electrical system. Switches can turn devices on and off based on requirements. The symbol for On is I ( a straight line) and the symbol for Off is O (a circle).

Connectors are used to connect different parts of the circuit to allow for a smooth flow of electrical signals. A male connector is denoted by a straight line with an arrowhead. Whereas a female connector is demoted by a straight line with an inverted arrowhead. 

Role of Electrical Estimating Services Texas

The primary role of Electrical Estimating Services Texas is to assess all the costs of an electrical system in a particular project. An estimator assesses the scope of a project and analyses clients’ requirements to perform accurate cost estimates. They present a precise financial plan for any type of electrical project and prevent cost overruns and time delays.

USE YOUR KNOWLEDGE OF ELECTRICAL SYSTEMS TO MAKE CONSTRUCTION PROJECTS SMOOTHER AND SAFER!

To Conclude 

In conclusion, possessing the knowledge of Electronic Components and Their Symbols is essential. Knowing the fundamentals of electrical components is a must for an expert. Only then will they be able to perform accurate installation of an electrical system regardless of the project’s size? In this article, some of the main components have been discussed with their symbols. In addition to that, what functions they perform in a circuit has also been discussed.
