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

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
