What is Electronics and Its Importance?

Share:
The branch of engineering which deals with current conduction and control in a vacuum or gas or semiconductor is known as electronics.

In our fast developing society, Electronics has become the most important part of our daily lives.

This versatile tool can be of great importance in increasing production, efficiency, and control.


Electronics essentially deals with electronic devices and their utilization.

Electronics devices are being used for automation and quality control in homes, offices, institutions, industries, etc.

They are rapidly replacing the present vast army of workers employed in factory processing and assembly.

Importance of Electronics

Electronics has gained much importance due to its numerous applications.

The electronics devices are capable of performing the following functions:

Rectifications.

The conversion of alternating current (AC) to direct current (DC) is called rectification.

A rectifier is an electrical device that converts a.c. power into d.c. power with high efficiency.

This d.c. can be used for charging storage batteries, electroplating, etc.

Amplifications.

The process of raising the strength of a weak signal is called Amplification or Amplified or Amplify.

An amplifier is used in a radio-set where the weak audio signal is amplified so that it can be heard loudly.

Control.

Speed of a motor, voltage across a refrigerator, etc. can be automatically controlled with the help of Electronics devices.

Generation.

Electronic devices can convert DC power into AC power of any frequency, they are called oscillators.

The oscillators are used in a wide variety of ways, electronic high frequency heating is used extensively in the metalworking industry for annealing and hardening.

Convertion of Light into Electricity.

Electronic devices can convert light into visible electricity, is known as photo-electricity.

These devices are used in Burglar alarms, sound recording on motion pictures, etc.

Convertion of Electricity into Light.

Electronic devices can convert electricity into visible light.

This valuable property is utilized in television, radar, etc.
