2. THINGS WORKING FROM
ELECTRICITY

3. HOW WE GET ELECTRICITY?
Main Electricity-Fridge, Washing Machine, Television,
Computer, Microwave, Toaster etc works from main electricity.
Cell-Camera, Mobile phone, Video Camera, Watch, TV
Remote, Toys etc works from cell.

4. ELECTRIC CELL
•Positive Terminal have Metal Cap.
•Negative Terminal have Metal Disc.

5. INSIDE A DRY CELL
A dry cell is a source of electric current that
contains a semi-solid ingredient. Electric
circuit: A path for an electric current to flow
is called an electric circuit.

6. ELECTRIC BULB
An electric bulb is a device which produces light when electricity is
passed through its terminals. The bulb has two thick contact wires in
the center with a thin wire attached between them. A bulb is said to be
fused if the filament gets broken.

7. CFL AND LED BULB
CFL
CFL is known as "Compact
Fluorescent Light" bulb. It gives
more energy than other bulbs, but
slightly lower than the LED.
LED
LED is known as “Light-emitting
diode”. CFL bulbs are made up of
argon and mercury in small
quantities. They are used in
offices, shops, houses and
schools for lighting purposes.

8. SIMPLE ELECTRIC CIRCUIT
A simple circuit have:-
 Bulb
 Switch
 Battery
 Wire

9. ELECTRICAL SYMBOLS

10. SIMPLE CIRCUIT USING SYMBOLS

11. OPEN CIRCUIT AND CLOSE CIRCUIT
OPEN CIRCUIT
An open circuit is one
where the continuity
has been broken by an
interruption in the path
for current to flow.
CLOSED CIRCUIT
A closed circuit is one
that is complete, with
good continuity
throughout.
