What are Electronic Components?

Electronic components :

Electronic components are the elements of circuits that help in their functioning. They can be classified into two categories, i.e., Active Components and Passive Components. Active elements are ones that offer gains. For instance, they could offer energy sources to circuits. Contrary to passive components, they can’t grow, and therefore cannot provide an energy stream throughout the entire course.

Passive components cannot amplify or enhance the intensity of the signal being afflicted them. Instead, they reduce the power, while active ingredients are able to energize and amplify the signal. What are Electronic Components?What are Electronic Components?

Overview of electronic circuits:

An electronic circuit is a device that controls and directs electric current to carry out a variety of tasks, such as data transfer, calculation, and signal amplification. It is made up of a variety of parts, including diodes, resistors, transistors, capacitors, inductors, and resistors. The components are linked together using conductive cables or traces. A circuit, however, can only be said to be finished if it forms a loop and begins and finishes at the same location.

Examples of Electronic Components

Transistors and amplifiers, for example, are active components. But, inductors, capacitors, and resistors are passive elements because they do not supply energy to the circuit.

Relevance of the Resistor

Consider the circuit with a diode and a voltage source at the input to see the importance of a resistor. The diode could be damaged in the event that the current flowing through it increases.

A circuit break could result in the issue getting worse. In order to protect the diode, it is crucial to lowering the current flow through it.

An inductor and capacitor, which store the energy produced by an active device, are other significant passive device. When the device is turned on, the energy from the sources will flow if the inductor and capacitor are not connected to the circuit, which will cause the hovering to halt. Power won’t be stored in the circuit in any way as a result. Only if we can utilize the energy saved while the source is not operating will this processing be beneficial.

While an inductor stores energy in the form of a magnetic field, a capacitor stores energy in the form of an electric field. The capacitor starts to charge and eventually reaches its maximum charge when the power source is turned ON. In the event that the active reference is turned off, the capacitor begins to set and will power the circuit even if the power source is turned off.

The inductor performs the same function in a similar manner. But because the energy is kept in a magnetic field, it is conserved.

Differentiating Electronic Components

Various types of electronic components can be identified based on factors like power supply components, measurement components, and other factors.

Based on the design structure, the following elements are essential: diodes, capacitors, resistors, transistors, and inductors. LEDs, for instance. These are the essential parts of a circuit because without them it cannot operate or be processed properly.
Power supply components: These elements include signal generators for DC power supplies and AC power supplies. Due to the fact that they power circuits, they are also regarded as active parts.
instruments for measurement Millimeters and cathode ray oscilloscopes are the most used tools for analyzing electronic circuits.
The various kinds of electronic components are depicted in the diagram above. Let’s examine each one in more detail.

Active Elements

Power for the circuit is provided by active components. What devices that fall under this category have already been covered? Let’s examine a handful of these gadgets in more detail.

I) Transistor:What are Electronic Components?

“Transfer” and “Resistor” combine to form a transistor. It is a technique for moving resistance inside the circuit from one area to another. When the input side resistance is high, the outer resistance is lower. The transistor is a three-terminal electronic component with switch and amplifier capabilities. It is managed by voltage or current. As a result, it is known as a voltage-controlled device or a current-controlled device. What are Electronic Components?

(ii) Batteries:

Internal electrochemical reactions in batteries enable them to generate electrical energy. To convert electro-energy into chemical energy, the chemical components inside the batteries undergo a change. It is a crucial component of any electrical circuit because, without electricity, the circuits cannot process signals.

An image tube used in television circuits is the cathode ray tube (iii). A controlled electronic weapon is used. The phosphor screen is vividly lighted as electron beams strike it.

Discretionary Elements
They are the components that obstruct the movement of energy or current.

The following sentences provide a list of some of the most common passive devices:

I Resistor: Resistors have the ability to keep current flow from being obstructed or hindered. Typically, resistors are utilized as wind limiters to safeguard active components from degrading.

In order to prevent any current flow that could be able to escape the active components, resistance is attached to them. The resistance also acts as an additional stress.

(ii) An inductor, which allows DC to pass through while obstructing AC. It has a low DC resistance and a high AC resistance. Because of this, it is used in equipment for applications where AC ripples are undesirable. Additionally, it holds energy as a magnetic field.

(iii) Capacitor:

A capacitor stores electric charge in circuits. It is essential in circuits for rectifiers, filters, etc. Additionally, the voltage regulator circuit needs capacitors’ ability to provide standard AC and high resistance DC reactions. The AC ripples are also filtered.

They are necessary because, without these inactive devices, active devices cannot function as intended. For instance, a transistor cannot amplify weak signals without the assistance of a load resistor. It functions passively. As a result, these components are crucial in electrical circuits.


Electronic devices influence practically every part of our life, from brewing a hot cup of coffee to conversing with loved ones who reside on other continents.
