oh no
there is no electricity I was just about
to finish my game
have to restart it now food
seems like there is still a problem in the
electricity supplies
Don't worry it'll be back in a moment. Wow
it's back.We can't  on do anything without
electricity
these days .Yeah, but do you know  from where your  electricity comes
from?  I think it comes from that switch !
Right?
You are very right!Electricity comes to this TV from this switch.
But what about the source of all the  electricity
that comes to everyone's home?Let me ask my
friends
Do you know where electricity comes from
Do you want to k now the sources of it and how it is produced?
Ok,ok.Take a look here.
What is this?
This is a coil of wire and a magnet mounted on a shaft.
What it is used for?It is used to produce electricity.
But how? If we spin a magnet around with-in a coil of wire
electricity is produced  in the wire.
Oh, it is so simple!
All we need to have is a coil of wire
and a magnet to make electricity. And just spin the magnet with-in the coil.
This process is known as electromagnetic
induction
Can I spin this magnet? Oh yes!
But let me  first attach a small electric bulb with the wires.
Now you can spin the magnet with the help of the handle.
Wow ,the bulb is on!
So guys now you know the basics of
producing electricity !
Now something to remember ! The machine
having a magnet and coil of wire ,in this way, is known
as generator .So we need a generator   like this to produce electricity?
Yes, in most of the cases a generator is
required.
Wow ! Now I can produce electricity
electricity for my entire home
with this generator . But see,this is too small !
This can light up only a small bulb.
You need a big generator for getting more electricity.
Let me show you !
Oh ,it does not look like the earlier generator!
Let's peep inside!
Oh yes, it also has a big magnet
linked with a shaft and wires all around it.
Remember every generator has this
kind of arrangement inside it.
Hmmm, if I spin this generator shaft
I can light up my entire home !
Hmmm, now try to move it.
Ah
Ah
I can't spin it.
It is very heavy to move.
Now have a look at these giant generators!
Oh,wow! That's so huge.Yeah,these big generators are used to produce electricity
for a whole city.But how do they spin the magnet inside these big generators?
I can't even move the smaller one!
To move the magnet inside the big
generator
a big fan is attached to this shaft.
A big fan?  Yeah, look here.
These big bands are called
turbines. Turbines?
Yeah,turbines.
Friends! hope you remember generator ,the
machine to make electricity !
now I remember turbine that is the
second most important tool
A turbine helps the generator to work
so that it can produce electricity.
But how does this fan,I mean turbine help
in turning the generator?Look here!
 
In some cases ,a lot of water is poured over this
The flowing  water makes it turn.When the turbine moves,
shaft of the generator also moves.
Wow ! so water helps in running the generator! You got it right! The electricity
is generated with  the help of the water .This kind of electricity is known as hydroelectricity
The word hydro means related to water.
But to turn a big generator ,we may need a lot of water?
From where  all this water  will come ?
For that ,we need to visit a dam.
Dam?What is a dam?Let's go and see !
 
Wow! There is a lot of water here!Seems like water is being stopped here!
Yes, it is a kind of a barrier to
to stop river water.Lot of water is collected
here.  But why? Well
Jimmy ,this stored water is used either for
water supplies or for generating electricity.Oh !
That is why there are a lot of turbines
and generators  nearby!
This is called hydro-electric plant.
Water from higher level  flows into a pipe that carries it down
to a turbine.As water moves down ,it gains a lot of pressure
This flowing water drives the  turbine
that is connected to the generator.And inside the generator ,
there is a large electromagnet
in the coil of copper wire.
When this magnet rotates inside the coil of wire.
electricity is produced.Then it is sent to our homes
through transmission lines.Wow! It is so clear to me
Water from the dam
moves the turbine,turbine drives the generator. And generator
produces the electricity.Guys,
have a closer look.This is how water helps in producing electricity.
me visit do the damn let interesting
but camby is any are deleted on the
turbine
yet down many believe in many cases
it is moved by 15 ski you much how Kim
scheme rules
any plane
it all look at this Kenya finnick
eat is very simple have to be 07
NT Wright see
anticipating feeling deadline
we need them home on one Daniel
made you sexcii Union the mitigation
bomber like 10 only yeah steam is a
gas it is just like any you
let me try to make this stop by spin
0 he did not even Red Bull winch
kid it is very heavy we need not
depression
Remi no I don't need to move it but some
they have really get that much of
0
in more to be electricity generating
plants what
if put in Big Bang being it is blind to
produce steam and take care bye
is moved with the creation of 15 like my
a meal yet now let's see how the whole
system black
like your
is eating I'm kit Jenny sistine and st.
moves Dec 2009
that Spain's shaft connected to a
maddening inside the final blinds
bad can you name the fuel used for
heating the wanted to do
team me can use electricity to heat
water
like we used to take fine and he's a act
or
here right like using electricity to
produce electricity can be baby costly
think not me
we can use coolly Kenyan we can use
own we can also use natural gas if but I
owe my life
are you paying him thatcher I doors
fossil fuels
so we can you just call it and natural
gas as fuel
to be able to walk out you can use team
don't look down by
yet kathleen you think each student you
electricity these is also called
permanent enmity
and this is done income made plans
correct
but that lunch where we use uranium F
you want to produce electricity
I'm known as nuclear power plant from
I am by eight bring when
in finding all for sale feel its main
gate
all well then there would be no
electricity in this wind
from even find itself by me the
our finding new ways to generate
electricity my
am now formally 250 is being produced a
handful
wing and live in fact mom
that is a complete can you tell me more
about peace
okay you can this is going to wind me
he believes om windmill def to buying
didn't need to move due to the wind 0
still we don't feeling we can generate
the electricity
now tell me about the Wii's to get
electricity from the Sun
yea read it
feet goodnight for on special plan is
God
for duplicate fans be faulted use
electricity
while buchanan et tu City
far in finite PDF file name: and Sun
has bball only speaking feel bad from
home but
like dumb what
feel big deal is on dance and
electromagnetic induction
