00:00:00,000 --> 00:00:02,759
Hello, we are going to talk to you about our project.

2
00:00:03,359 --> 00:00:06,099
It is a mixture of a windmill and a lighthouse.

3
00:00:07,480 --> 00:00:10,060
We are the group B of Primera de la ESO Day.

4
00:00:10,679 --> 00:00:15,580
Our names are Manuel, Daniel, Nayán, Eva and Teo.

5
00:00:16,019 --> 00:00:19,559
We have done this project to show you how electricity works.

6
00:00:20,679 --> 00:00:23,280
We are going to tell you what a circuit does.

7
00:00:24,339 --> 00:00:29,980
A circuit transforms electrical energy into a different kind of energy.

8
00:00:30,000 --> 00:00:37,579
A circuit has four components, power source, conductors, load devices and control devices.

9
00:00:38,640 --> 00:00:40,320
This is how the project works.

10
00:00:41,280 --> 00:00:43,200
It has two different circuits.

11
00:00:43,539 --> 00:00:48,719
In this circuit we transform chemical energy from the power source to electrical energy.

12
00:00:49,399 --> 00:00:52,920
Then the busser transforms it into sound energy.

13
00:00:53,460 --> 00:00:56,479
Each power source is a cell of 4.5 volts.

14
00:00:56,479 --> 00:01:02,479
A power source is a component that supplies energy to the rest of the circuit.

15
00:01:02,479 --> 00:01:06,480
The conductors are wires made up of bronze.

16
00:01:06,480 --> 00:01:11,480
They transport the energy from the power source to the load devices.

17
00:01:11,480 --> 00:01:15,480
The control device is a normally open push switch.

18
00:01:15,480 --> 00:01:20,480
The control device is a device that makes the circuit be open or closed.

19
00:01:20,480 --> 00:01:24,480
When it is not pressed, the load device doesn't work.

20
00:01:24,480 --> 00:01:29,939
But when it is pressed, the circuit becomes closed and the load devices work.

21
00:01:30,519 --> 00:01:32,200
There is another circuit.

22
00:01:32,980 --> 00:01:38,459
The generator transforms the eolic energy into electrical energy.

23
00:01:39,000 --> 00:01:42,480
The cell transforms chemical energy to electrical energy.

24
00:01:43,319 --> 00:01:48,079
All the electrical energy works together to produce light energy.

25
00:01:48,079 --> 00:01:55,079
It consists of a cell of 1.5 volts and a generator as power sources.

26
00:01:55,079 --> 00:02:03,079
The generator is a motor that works as a power source, because the movement of the blade produces energy, like an electric central.

27
00:02:03,079 --> 00:02:07,079
The conductors are bronze wires.

28
00:02:07,079 --> 00:02:10,080
The load device is a red led.

29
00:02:10,080 --> 00:02:16,080
It works as a conductor under 2 volts, but as a load device over 2 volts.

30
00:02:16,620 --> 00:02:18,759
That's why it is a semiconductor.

31
00:02:19,659 --> 00:02:22,460
The generator is imposed by a hair dryer.

32
00:02:23,460 --> 00:02:27,280
The cell is used to add more energy for the LED to light.

33
00:02:28,000 --> 00:02:29,599
We hope you like it.

34
00:02:30,340 --> 00:02:30,759
Bye!
