The document explains the importance of electricity in daily life, including its use in lighting homes, offices, and streets. It describes how electricity is generated at power plants and transmitted through various components like transformers and distribution lines. Additionally, it discusses electric cells, their structure, and how they produce electricity from stored chemicals, as well as their applications in devices like torches and clocks.

2. We use electricity for many
easier.
purposes to make our tasks

3. Electricity makes it possible to light
Our House Office

4. Electricity makes it possible to light

6. Electricity helps us to study in light

7. helps to Lift water from Well/Ground

8. How do we get
Electricity in our
Home ?

9. How do we get
Electricity in our
Home ?
Power Plant- Power
House, Where electricity is
generated.
Transmission Line
Transformer
Distribution Line
Home

10. However ,the supply of
electricity may fail or it may not
be available at some places.
In that case we use Torch

11. TORCH
Cell
Bulb
Switch

12. Where does the torch
get electricity from?

13. • Electricity to the bulb
in a torch is provided
by the Electric cell.
• Electric cells are also
used in alarm clocks,
wristwatches, and
many other devices.

14. Electric Cell
Metal Cap
Metal Disc
Have you ever carefully looked at an electric cell?
You might have noticed that it has a small metal cap on
one side and a metal disc on the other side

15. Did you notice a positive (+) sign and a negative (–)
sign marked on the electric cell
All electric cells
have two terminals
a) Positive terminal
b) Negative terminal
(Positive Terminal)
Metal Cap
(Negative Terminal)
Metal Disc

16. So An electric cell produces
electricity from the
chemicals stored inside it.
When the chemicals in the
electric cell are used up, the
electric cell stops producing
electricity.
Now you may think that how An electric cell produces electricity ?
