3. ELECTRICITY
ELCTRITY IS THE BASIC NEED OF THE HUMAN
FOR TODAY AS OUR LIFE IS MOSTLY DEPENDENT
ON THE ELECTRIC EQUIPMENT AS REFRIDGERA-
TOR,T.V.,MOBILE .

5. ELECTRICITY
 IT CAN BE OBTAIN BY TWO BASIC
SOURCESWHICH ARE ADS
FOLLOWS :
1. CELL
2. GENERATOR

6. CELL
 CELL ARE USED FOR THE LOW
POWER SUPPLY .
 BY THE CELL ELECTRONIC
EQUIPMENT LIKE : WATCH,REMOTE
CAN BE OPERATED.

7. CELL HAS TWO TYPES
 PRIMARY CELL  SECONDARY CELL

8. PRIMARY CELL
 PRIMARY CELL IS
A CELL WHICH IS
DESIGNED TO BE
USED ONCE AND
DISCARDED .
 IT IS CHEAP IN
PRICE ALSO
MAINLY SILICON IS
USED IN THIS .

9. SECONDARY CELL
 SECONDARY CELL
IS A TYPE OF CELL
WHICH CAN BE
CHARGED
,DISCHARGED
INTO A LOAD .

10.  In this type of cell electric energy is
converted in the chemical energy
by the electricity .
 This process is called charging of
cell.
 While the use ,the chemical energy
is again converted in electric
energy .
 This process is called discharge.

11. GENERATOR
 GENERATOR IS USED FOR THE
HEAVY POWER SUPPLY MEANS FOIR
THE HEAVY DUTY PURPOSE .
 IN THE FUNCTIONS,CORPORATES
HEAVY POWER IS REQUIRED SO
GENERATOR IS USED

13. BASIC STRUCTURTE OF
GENERATOR
 IN THE GENERATOR
GENERALLY AN
ARMATURE ROTATES
BETWEEN TWO
MAGNETS .
 DUE TO THIS ROTATION
PROCES ELECTRICY IS
PRODUCES.
