Basic Facts, Role, and Functions of Electronic Devices

The importance of electronics lies in its significant impact on our lives. The wide range of electronic applications has greatly contributed to increased efficiency and time-saving measures. Electronic gadgets and machinery are considered valuable tools for enhancing efficiency and productivity.

Electronics have become an essential part of our lives, as they not only fulfill our individual needs but also contribute to the overall growth of technology and the economy. Inventions and innovations heavily rely on advancements in electronics. Therefore, electronics hold immense importance in today’s world.

The following are the main functions that electronics tend to perform:


The procedure of converting alternating current (AC) into direct current (DC) is known as rectification. Electronic devices can efficiently and easily convert AC current into DC current, serving purposes such as electroplating and battery charging.


Electronic devices enable the amplification of weak signals. Amplifiers can reinforce signals, allowing them to be heard more loudly, as exemplified by using an amplifier in a radio set.


Electronic devices find extensive applications in automatic control systems. Stabilizers, for instance, are utilized to control the voltage across an air conditioner, ensuring stable operation.


Electronic devices have the capability to convert AC power into DC power with a specific frequency. Such devices are commonly referred to as oscillators when they perform this function.
