The Branch of Engineering which deals with Current Conduction through a Vaccume or Gas or Semiconductor is known as Electronics.

Electronics mainly deals with Electronics Devices and their utilization.Such Devices have valuable properties which enable them to function and behave as
the friend of Human today.

Electronics has gained much importance due to its numerous application in Industry.

The Electronics Devices are capable of performing various functions.Out of that the main functions are as below.

01)Amplification:-

The process of raising the Strength of Weak Signals to Strong Signals is known as Amplification.An Amplifire,is used in Radio-Set where the Weak Signals
are Amplified so that it can be heard loudly.

02)Rectification:-

The conversion of Alternetive Current (a.c.) into Direct Current (d.c.) is called Rectification.Electronics Device can convert a.c.Power  into d.c. Power with
very high efficiency.This d.c. supply can be used for Charging Storage Batteries,Field Supply of D.C.Generators,Electroplating etc..

03)Conversion of Light into Electricity:-

This Conversion of Light into Electricity is known as Photo-Electricity.Photo-Electric Devices are used in Sound Recording on Motion Pictures etc..

04)Generation:-

Electronics Devices can convert d.c. Power into a.c. Power of any Frequency.When performing this function,they are known as Oscillators.
Electronics High Frequency Heating is used for Annealing and Hardening.

05)Control:-

Electronics Devices find wide applications in Automatic Control.For example,Speed of Motor,Voltage accross Refrigerator etc.. can be Automatically
Controlled with the help of Such Electronics Devices.
