There are numerous basic electronic components that are used for building electronic circuits. These components include resistors, diodes, capacitors, integrated circuits, and so on. Some of these components consist of two or more terminals that are soldered to circuit boards. Some may be packaged types like integrated circuits in which different semiconductor devices are integrated.
Here is a brief overview of each of these basic electronic components and you can get in-depth information by clicking links attached to each component. Electronic components are basic discrete devices in any electronic system to use in electronics otherwise different associated fields. These components are basic elements that are used to design electrical and electronic circuits. These components have a minimum of two terminals which are used to connect to the circuit.
The classification of electronic components can be done based on applications like active, passive, and electromechanical. In designing an electronic circuit following are taken into consideration:. These components are used to amplify electrical signals to generate electric power.
The functioning of these components can be done like an AC circuit within electronic devices to protect from voltage and enhanced power.
An active component executes its functions because it is power-driven through an electricity source. All these components require some energy source that is normally removed from a DC circuit. As a result, they cannot amplify, although they can increase a current otherwise voltage or current. These components use an electrical signal to make some mechanical changes like rotating a motor. Generally, these components use electrical current to form a magnetic field so that physical movement can be caused.
Different types of switches and relays are applicable in these kinds of components. The devices which have the process of electrical as well as mechanical are electromechanical devices. An electromechanical component is operated manually to generate electrical output through the mechanical movement. These components can store or maintains energy either in the form of current or voltage.
Some of these components are discussed below. A resistor is a two-terminal passive electronics component, used to oppose or limit the current. The units of the resistance are ohms Where R is the constant called resistance. Resistors are further classified based on the following specifications such as the power rating, type of material used, and resistance value. These resistor types are used for different applications.
This type of resistor is used to set the right conditions in an electronic circuit. The values of resistance in fixed resistors are determined during the design phase of the circuit, based on this there is no need to adjust the circuit. A device that is used to change the resistance according to our requirements in an electronic circuit is known as a variable resistor.
These resistors comprise a fixed resistor element and a slider that taps on to the resistor element. Variable resistors are commonly used as a three-terminal device for calibration of the device. A capacitor made from two conductive plates with an insulator between them and it stores electrical energy in the form of an electric field. A capacitor blocks the DC signals and allows the AC signals and also used with a resistor in a timing circuit. These capacitors are of different types like film, ceramic, electrolytic, and variable capacitors.
For finding its value number and color-coding methods are used and it also possible to find the capacitance value with LCR meters.

An Integrated circuit is a special component that is fabricated with thousands of transistors, resistors, diodes, and other electronic components on a tiny silicon chip.
These are the building blocks of current electronic devices like cell phones, computers, etc. These can be analog or digital integrated circuits. These can be classified as linear and nonlinear ICs depending on its application. Please refer to this link to Know more about integrated circuits. LCD: A liquid crystal display LCD is a flat display technology, which is mostly used in applications like computer monitors, cell phone displays, calculators, etc.
This technology uses two polarized filters and electrodes to selectively disable or enable the light to pass from reflective backing to the eyes of the viewer. Please refer to this link to Know more about LCD. The display like 16X2 LCD is the most frequently used module in electrical as well as electronic circuits. This kind of display includes 2 rows and 16 columns so it is known as an alphanumeric display.
This kind of display is used to show the highest of 32 characters. Please refer to this link to know more about 16 X 2 LCD. Cathode ray tube display technology is mostly used in televisions and computer screens that work 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 the flattened surface has external components as an electron gun, electron beam, and a phosphorescent screen. Please refer to this link to Know more about cathode-ray tube. In electronic circuits, the DC power supply is very essential which is used as one kind of power source.
The major electronic components work with DC power supply because it is a consistent power source. A wall adapter is used as an alternate to the DC power supply in some projects which require 5V otherwise 12V. The battery is one kind of electrical energy storage device.
This device is used to change the energy from chemical to electrical to supply the power to various electronic devices like mobile phones, flashlights, laptops, etc. These consist of one or more cells and each cell contains an anode, cathode, and electrolyte. Batteries are available in various sizes which are also divided into primary as well as secondary. Please refer to this link to Know more about Batteries. An electromagnetic switch like the relay is used to operate the circuits electronically otherwise electromechanically.
A relay uses less amount of currents to operate so generally they are used to change low currents within a control circuit.
But relays can also be used for controlling high electric currents. A relay switch can be operated through a less current to switch ON a different circuit. These are either solid-state or electromechanical relays. An EMR or electromechanical relay includes a coil, frame, contacts, and armature, spring. A copper wire or coil is wounded around a metal rod to produce a magnetic field that moves the armature. The conducting parts like contacts are used to close and open the circuit.
These relays are very popular because they are inexpensive, reliable, and very fast as compared with electromechanical relays. Please refer to this link to know more about relay. The term LED stands for light-emitting diode. It is a semiconductor device used to emit light whenever a current supply flows through it.
In the semiconductor material, the charge carriers like electrons and holes combine then light can be generated. When light generates in the solid semiconductor material then these LEDs can be known as solid-state devices.

A switch is one kind of electrical component, used to connect or disconnect the conducting lane within the circuit so that electric current can be supplied or interrupted from one conductor to another. An electromechanical device is the most common kind of switch that comprises one or more electrical contacts that are movable and connected to other circuits. Once the set of contacts in the circuit are connected then there is a flow of current.
Similarly, when the contacts are disconnected then there is no flow of current.

This can be a challenging task, because different components call for different test procedures. Mobile circuit boards are generally more comfortable to use than television boards. Wires connected at 'crossroads' should be staggered slightly to form two tin whiskers on printed circuit boards consequences for. A multimeter that can check resistance can also be helpful, providing the resistor is already removed from the board measuring it while still soldered in can give inaccurate results, due to connections with the rest of the circuit.
