Electronic products have become an important part of our daily lives. Knowingly or unknowingly, we have become dependent on these gadgets for our day-to-day activities. They make our lives simple by converting tough tasks into easy. Have you ever wondered how these electronic products work?
These products have their ways of functioning which revolve around an electronic circuit. There must have been times when you would have tried fixing your broken electronic piece.
You must have come across chips and the circuit board consisting of various small and big electronic components. These components are the building blocks of an electronic device or an electronic circuit.
Today, electronic devices are created by using a huge variety of components. Some components like capacitors and resistors are simple while others like CPU chips is highly complicated and consists of over 20 billion transistors. Different components are linked together by printed metal connections or cables to create a piece of working electronic equipment.
An electronic component is basically a physical entity or discreet device in an electronic system which is used to affect the electronics and their associated fields.
These components are majorly industrial products that are available in a singular form. They are electronic devices or parts which are generally packed in a discreet way with two or more metallic pads or connecting leads.
These are connected together by a soldering to PCB or Printed Circuit Board to create an electric circuit with a specific function. There are different basic electronic components India that are used in building the electronic circuits.
Absence of these components makes the electronic circuit incomplete and lead to their malfunctioning. While some of these come as a package such as integrated circuits which consists of integrated various semiconductor devices.
However, these components should not be confused with the electrical elements that are conceptual abstractions mainly representing idealized electronic components. These components have a large number of electrical leads or terminals.
These leads further connect to the other electrical components, generally over a wire to create an electronic circuit such as radio receiver, oscillator, amplifier, etc. Electronic components are those elements of the circuit which help in its functioning.
They usually have a minimum of two terminals that are used to connect the electronic circuit. The electronic components are further divided into active, passive, and electromechanical based on their application. Further, you will get to read what this means and what makes Tesca Technologies the best component supplier.
Components of Electronic Component
Electronic components are of different types and can be classified as active, passive, and electromechanical components. They are distinct from each other and have their own speciality according to which they are used in the circuit.
Active Components:
These electronic components are devices known to amplify the electric signal and for power production. These types of electronic components are used as an alternative current circuit in devices as they help in augmenting power and voltage.
They can execute operations as they are powered by a source of electricity. In simple terms, an active component is a component which supplies energy to the electronic circuit.
All the active components require some sort of energy which is generally extracted from a DC circuit. Any characteristic active component consists of an oscillator, integrated circuit, and a transistor. The components can be brought to function like an AC circuit within the devices to protect from enhanced power and voltage.
Commonly known active components are current sources, voltage sources, generators such as DC generators and alternators, different types of transistors and diodes. Here these active components from electronic components list are explained in detail.

Current Sources
An electronic circuit which absorbs or delivers electric current free from the voltage across it is known as a current source. Current sources are generally of two types – independent current source and dependent current source.
An independent current source is that source which delivers constant current while a dependent current source is the one which delivers current that is proportional to some other current or voltage in the circuit. Current sources are uncommon in the circuit compared to voltage sources.
Voltage Sources
Voltage sources are those sources which generate an exact amount of output voltage which remains unchanged regardless of the actual current. It is a two-terminal device known for maintaining fixed voltage.
A voltage source which can maintain high voltage independent of the output current or load resistance is termed as an ideal voltage source.
Dual of the current source, a voltage source in real-world isn’t capable of supplying unlimited current. Voltage sources are generally divided into two – independent voltage source and dependent voltage source.
An independent voltage source is the one in which the voltage can be specified independently of any other present variable. However, if the voltage running across an ideal voltage source is determined by any other current or voltage in the circuit, then it is called controlled or dependent voltage source.
A mathematical model of the amplifier has been observed to include dependent voltage whose magnitude is known to be governed by fixed relation to an input signal.
The internal resistance capacity of an ideal voltage source is zero, it is capable of absorbing or delivering any amount of current. The current passing through the ideal voltage source is determined using the electric circuit.
When it is connected to an open circuit, the current is zero and thus so is power. Whereas when it is connected to a load resistance, the current passing through the source reaches infinity as the load resistance reaches zero. Therefore, an ideal voltage source is capable of supplying unlimited power.
Mainly, the sources of electrical energy are modelled as voltage sources. An ideal voltage source provides no energy when it is being loaded with an open circuit. However, when the load resistance approaches zero, it approaches infinite current and energy.
When compared to this, a current source provides constant current as long as it being connected to source terminals having a sufficiently low impedance.
An ideal current source generally provides no energy to the short circuit and is known to approach infinite voltage and energy as soon as the load resistance approaches infinity.
Current sources and voltage sources are said to be the duals of each other and any of these sources in their non-ideal form can be converted from one to the other.
Transistors
A transistor is basically a semiconductor device which is used to switch or amplify electronic power or signals. It is created using the semiconductor material usually with the presence of at least three terminals for the connection to an external circuit.
Any current or voltage applied to the one pair of the transistor’s terminals is known to control the current passing through another pair of terminals.
A transistor can amplify a signal because the output or controlled power can be higher than the input or controlling power. It is known to have revolutionized the entire field of electronics and paved the way for calculators, computers, and radios among others. Mostly, transistors are made up of pure silicon, germanium, and other semiconductor materials.
Passive Components
These types of electronic components can’t introduce net energy into the circuit neither they rely on a particular source of power except what is available to them from the AC circuit.
They cannot increase the power of the signal; however, they may increase current or voltage as it is done by a resonant circuit or transformer. These components include two-terminal components like resistors, transformers, inductors, and capacitors.
Resistors
Resistors are basically a two-terminal passive electronic component which is used to either limit or oppose the current. It works on the basis of Ohm’s law which says that any voltage which is applied across the resistor’s terminals is directly proportional to the current flowing through it.
There are different types of resistors based on the type of material used, power rating, and resistance value. These are fixed resistors and variable resistors – fixed resistors are useda for setting the right conditions in an electronic circuit. The value of resistance in a fixed resistor is said to be determined during the design phase of the electronic circuit.

A variable resistor is a device which is used for changing the resistance according to the requirements. This resistor consists of a fixed resistor element along with a slider that taps on the resistor element. These elements are commonly used as a three-terminal device for the device’s calibration.
Capacitors
A capacitor is made using two conductive plates consisting of an insulator between them. It is used to store electrical energy in the form of an electric field. A capacitor allows the AC signal and blocks the DC signal, it is used with a resistor in a timing circuit.
Inductors
Inductors are also known as AC resistors; they store electrical energy in the form of magnetic energy. Some other passive electronic components comprise of various sensors, antennas, motors, memristors, etc.
Electromechanical Components – To make mechanical changes, these components use the electric signal. Usually, the electric current is used by these types of electronic components to form a magnetic field to create physical movement.
These electronic components consist of various types of switches and relays. These devices can be easily identified where you find electrical as well as a mechanical process. These are operated manually for the generation of electrical output by mechanical movement.
