This is a Clilstore unit. You can .
oh no there is no electricity
I was just about to finish my game I
love to restart it now
hmm seems like there is some problem and
electricity supplies
don't worry it'll be back in a moment
Wow
its back we can't do anything without
electricity these days
yeah but do you know 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 know about the sources of it and how it is produced
okay okay take a look here
what's this this is a coil of wire and
magnet mounted on a shaft
what is it used for it is used to
produce electricity but how if we been a magnet around within a coil of wire electricity is produced in the wire always so simple all we need to have is a quiet of violence and a magnet to make electricity and just been the magnet within the court this process is known as electromagnetic
induction
can I spend 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 BB is on
so guys now you know the basics of producing electricity now something tonremember the Machine having a magnet and a coil of wire in this way is known as generator so we need a generator like this to produce electricity
yep in most of the cases a generator is required
Wow now I can't reduce electricity for my entire home with this generator but see this is too small
this can light up only a small bump you need a big generator for getting more electricity
let me show you
35
00:02:48,590 --> 00:02:54,290
oh it does not look like the audio
generator
36
00:02:55,790 --> 00:02:58,790
let's keep inside
37
00:03:00,590 --> 00:03:08,930
oh yeah it also has a big magnet late
with the shaft and wires all around it
38
00:03:08,930 --> 00:03:13,280
remember every generator has this kind
of arrangement inside it
39
00:03:13,819 --> 00:03:17,510
hmm if i spend the generator shaft
40
00:03:17,510 --> 00:03:20,540
I could like up my end dial home
41
00:03:20,540 --> 00:03:23,540
hmm now try to move it
42
00:03:28,900 --> 00:03:31,240
yeah
43
00:03:31,240 --> 00:03:32,660
huh
44
00:03:32,660 --> 00:03:41,420
we can spin it is very heavy to move now
have a look at these giant generators
45
00:03:41,420 --> 00:03:49,310
oh wow that so you just hear these big
generators I used to produce electricity
46
00:03:49,310 --> 00:03:51,290
for the whole city
47
00:03:51,290 --> 00:03:55,430
but how do they spin a magnet inside
these big generators
48
00:03:55,430 --> 00:04:00,620
I can't even move the smaller one to
move the magnet inside the big
49
00:04:00,620 --> 00:04:06,350
generators a big fan is attached to this
shaft a big fan
50
00:04:07,010 --> 00:04:18,380
yeah look here these big fans of calls
tell binds toe bite bites
51
00:04:19,209 --> 00:04:23,830
friends hope you remember generator the
machine to make electricity
52
00:04:24,550 --> 00:04:30,789
now remember turbine that is the second
most important to a turbine helps the
53
00:04:30,789 --> 00:04:37,479
generator to work so that it can produce
electricity but how does this fan
54
00:04:38,199 --> 00:04:43,419
I mean dog by help and donning the
generate don't you care
55
00:04:44,150 --> 00:04:51,890
in some cases lot of water is dropped on
this
56
00:04:51,890 --> 00:04:56,690
the water makes it down when the
deadline moves shaft of the generator
57
00:04:56,690 --> 00:04:58,280
all saloon
58
00:04:58,280 --> 00:05:02,150
wow so water helps and running the
generator .
59
00:05:02,870 --> 00:05:08,930
you got it right electricity is
generated with the help of the water
60
00:05:08,930 --> 00:05:14,600
this kind of electricity is known as
hydro electricity the word hydro means
61
00:05:14,600 --> 00:05:19,040
related to water but to turn a big
generator
62
00:05:19,040 --> 00:05:23,090
we may need a lot of water well all this
water come from
63
00:05:23,870 --> 00:05:29,360
for that we need to go to a damn damn
what is her damn
64
00:05:29,360 --> 00:05:39,560
let's go and see wow there's a lot of
water seems like water is being stopped
65
00:05:39,560 --> 00:05:40,460
deal
66
00:05:40,460 --> 00:05:46,880
yes it is a kind of a barrier to stop
river water lots of water is collected
67
00:05:46,880 --> 00:05:47,720
here
68
00:05:47,720 --> 00:05:55,640
but why well Jimmy this stored water is
used for water supply all for generating
69
00:05:55,640 --> 00:05:56,810
electricity
70
00:05:56,810 --> 00:06:04,310
oh that is why there are lots of
turbines and generally does your by this
71
00:06:04,310 --> 00:06:05,120
is gone
72
00:06:05,120 --> 00:06:12,020
hydroelectric plants water from higher
level nose into apply that carries a
73
00:06:12,020 --> 00:06:15,260
down to Twitter bind as water move down
74
00:06:15,260 --> 00:06:20,390
it gained from the water pressure this
flowing water drives the turbines that
75
00:06:20,390 --> 00:06:24,620
is connected to the generator and inside
the generator
76
00:06:25,190 --> 00:06:31,940
there is a large electromagnet in the
coil of copper wild when this magnet
77
00:06:31,940 --> 00:06:34,760
rotates inside the call of file
78
00:06:34,760 --> 00:06:41,330
electricity is drug use then it is think
two homes through 12 mission lines
79
00:06:41,330 --> 00:06:44,600
wow it is so clear to me
80
00:06:44,600 --> 00:06:50,960
water from the dad moves the turbine
turbine drives the generator and
81
00:06:50,960 --> 00:06:56,330
generally docked reduces the electricity
guys have a closer look
82
00:06:56,840 --> 00:07:04,910
this is how water helps in producing
electricity their visit to the dam was
83
00:07:04,910 --> 00:07:10,760
interesting but Shelvey is there any
other way to toward the turbine yet
84
00:07:10,760 --> 00:07:18,230
there are many ways in many cases it is
moved by steam steam which how can steam
85
00:07:18,230 --> 00:07:20,249
move anything
86
00:07:20,249 --> 00:07:23,549
look at this can you spin it
87
00:07:23,549 --> 00:07:31,109
it is very simple I have to blow some
end to it see it is spinning
88
00:07:31,619 --> 00:07:36,100
it is the same with divine we need some
air or gas drilling
89
00:07:36,100 --> 00:07:41,260
but you said T - yeah seems contagious
form of water
90
00:07:41,260 --> 00:07:49,420
oh yeah steam is a gas it is just like
hmm let me try to make this store buying
91
00:07:49,420 --> 00:07:51,580
spin
92
00:07:51,580 --> 00:07:54,040
yeah
93
00:07:54,040 --> 00:07:57,040
oh it did not even move an inch
94
00:07:58,330 --> 00:08:01,810
it is very heavy we need a lot of
pressure
95
00:08:01,810 --> 00:08:07,210
we need not of had to move it but from
Beverly get that much of air
96
00:08:10,090 --> 00:08:15,730
in north of the electricity generating
plants water is put in big tanks then it
97
00:08:15,730 --> 00:08:20,949
is boys to produce team and the turbine
is moved with the pressure of the steam
98
00:08:20,949 --> 00:08:23,530
like my video
99
00:08:23,530 --> 00:08:27,430
yep now let's see how the whole system
works
100
00:08:29,560 --> 00:08:36,610
water is heated until eight reduce
esteem and this team moves the turbine
101
00:08:36,610 --> 00:08:43,570
that spins shaft connected to a magnet
inside the coin of while but can you
102
00:08:43,570 --> 00:08:49,630
name the fuel youthful heating the water
to produce team we can use electricity
103
00:08:49,630 --> 00:08:54,940
to heat water like we use it for our
Giza at home
104
00:08:54,940 --> 00:08:59,440
you're right but using electricity to
produce electricity can be very costly
105
00:08:59,440 --> 00:09:01,060
think more
106
00:09:01,060 --> 00:09:02,320
mmm
107
00:09:02,320 --> 00:09:06,520
we can you school - yeah we can use
phone
108
00:09:06,520 --> 00:09:14,590
we can also use natural gases biomass or
uranium etc are those fossil fuels
109
00:09:14,590 --> 00:09:21,400
so we can use school and natural gas as
fuel to heat the water to get you steam
110
00:09:21,400 --> 00:09:23,080
to turn the turbine
111
00:09:23,080 --> 00:09:27,430
yep and as we use the heat to reduce
electricity
112
00:09:28,030 --> 00:09:35,020
this is also called thermal energy and
this is done in common blondes correct
113
00:09:35,020 --> 00:09:38,860
but the plants where we use uranium as
fuel to produce electricity
114
00:09:39,760 --> 00:09:42,760
unknown as nuclear power plants
115
00:09:43,360 --> 00:09:51,850
I am boarded right well if five-day all
fossil fuels will get all then there
116
00:09:51,850 --> 00:09:54,310
would be no electricity in this world
117
00:09:54,310 --> 00:09:59,530
hm even scientists of worried they are
finding new ways to generate electricity
118
00:10:00,430 --> 00:10:06,880
like now some of the electricity is
being produced with the help of wind and
119
00:10:06,880 --> 00:10:08,230
even son
120
00:10:08,230 --> 00:10:13,540
wow that is great can you tell me more
about these but ok
121
00:10:13,540 --> 00:10:18,460
look at this is called a windmill the
blades of the windmill active stop
122
00:10:18,460 --> 00:10:21,610
buying the blades move due to the wind
123
00:10:21,610 --> 00:10:26,260
oh so we don't need fuel will generate
the electricity
124
00:10:26,920 --> 00:10:31,510
now tell me about the ways to get
electricity from the Sun
125
00:10:31,510 --> 00:10:32,990
here it is
126
00:10:32,990 --> 00:10:39,350
see sunlight falls on special panels
called photovoltaic sense these cells
127
00:10:39,350 --> 00:10:40,910
produce electricity
128
00:10:40,910 --> 00:10:47,839
wow we can get electricity for in finite
period for them and sun as they will
129
00:10:47,839 --> 00:10:49,399
always be there
130
00:10:49,399 --> 00:10:52,760
so guys some homework for you
131
00:10:52,760 --> 00:11:00,290
it is very easy what few videos on dance
& electro magnetic induction also click
132
00:11:00,290 --> 00:11:04,190
