Electronic devices have become companions in our daily lives. From mobile phones to household appliances, electronic devices have made our lives more convenient and comfortable. If you have ever held a mobile phone in your hands and wondered how an electronic device works, you are not alone. The majority of people don’t fully understand how electronic devices work.

Nearly every industry uses electronic devices to carry out a variety of activities. These devices are made up of electronic components that provide power and control to the device. Electrical circuits are what make electronics work.

Electronic Circuits

Electronic circuits are composed of a variety of electronic components. These components include Microcontrollers as main engine and assisted by host of other components resistors and capacitors, as well as diodes and transistors. A resistor restricts the flow of current, a capacitor stores an electrical charge, a diode allows the flow of current to be limited to one direction, and a transistor controls the flow of current. If you are searching for any of these electronic components online, you are at the end of your search. For all your electronic e-components visit Indus Technologies, the best electronic components distributors in Bangalore.

There are two kinds of circuits.

Printed Circuit Boards

In most electronic devices today, complex circuits are required. To create these circuits, designers need to carefully arrange the components on a printed circuit board (PCB). Many companies use PCBs to reduce manufacturing time and costs. Printed circuit boards are plastic boards whose layout is chemically printed on the surface.

Integrated Circuits

As technology advances, electronic devices become smaller and more powerful. These devices need complex circuits with thousands of components. In these situations, integrated circuits (ICs) are often used. An integrated circuit is a small circuit that fits inside a small silicon chip. An IC is used in mobile phones, laptops and other high-end electronic devices.

Types of Electronic Components

1. Passive Components

These are non-gain and non-directional components. They are also known as Electrical elements or electrical parts.

Examples: Resistors, Capacitors, Diodes, Inductors.

2. Active Components

These are gain or direction components.

Examples: Integrated Circuits or ICs, Transistors & Logic Gates.

Let us look at their functions to get an idea about their importance in e-devices.

The resistor is used to regulate the flow of electrical current within an electronic circuit. Resistance limits the current flow, divides the voltage, and modulates signal levels.

Capacitors are used to store and discharge electricity. They are commonly used for filtering signals, smoothing voltage variations, and storing charges for a variety of applications.

A diode is a device that permits the flow of current only in one direction. They are used in rectification (accelerating the flow of electrical current from an AC source to a DC source), in voltage control, and to demodulate signals in electronic devices.

In most electrical circuits, an inductor is used to store magnetic energy when an electric current passes through it.

In electronic circuits, a transistor is used as an inductor or a switch. Transistors can increase the strength of weak signals, control large currents, and carry out logical operations, making them a versatile part of modern electronics.

Integrated circuits (ICs), sometimes referred to as chips, microchips or microelectronic circuits, are semiconductor wafers containing thousands or millions of small-scale resistors (electrical resistors), capacitors (electrical capacitors), diodes (electrical diodes) and transistors.

Logic gates are an essential part of circuit design and a digital system. They are the building blocks of a digital system. A logical gate is an electronic circuit that has only one output. A logical gate can have one or more inputs, but most gates have two inputs.


Electronic components are the building blocks of modern devices, working collaboratively to perform various functions. These components include semiconductors like transistors for amplification and switching, resistors for controlling current, capacitors for storing charge, and integrated circuits for complex operations. By combining these elements strategically, devices can accomplish intricate tasks, from simple calculators to advanced smartphones and beyond, showcasing the remarkable synergy between different components in the realm of electronics.
