00:00:00,000 --> 00:00:01,000
Electric circuits components.

1
00:00:02,000 --> 00:00:06,000
There are four main groups of components in an electric circuit.

2
00:00:06,000 --> 00:00:07,000
Power source.

3
00:00:07,000 --> 00:00:08,000
Conductor.

4
00:00:08,000 --> 00:00:09,000
Load device and control devices.

5
00:00:10,000 --> 00:00:11,000
Power source.

6
00:00:11,000 --> 00:00:15,000
Component that supplies electrical energy to the rest of the circuit.

7
00:00:16,000 --> 00:00:17,000
Conductor.

8
00:00:17,000 --> 00:00:21,000
Component that transports the electrical energy from the power source to the load devices.

9
00:00:22,000 --> 00:00:23,000
Control device.

10
00:00:23,000 --> 00:00:28,000
Device that regulates the circuit allowing or preventing the flow of electric current through

11
00:00:28,000 --> 00:00:28,000
the circuit.

12
00:00:29,000 --> 00:00:30,000
Load device.

13
00:00:30,000 --> 00:00:35,000
Component that receives the electrical energy from the power source and converts it to other

14
00:00:35,000 --> 00:00:36,000
types of useful energy.

15
00:00:37,000 --> 00:00:39,000
Electrons cannot move spontaneously.

16
00:00:39,000 --> 00:00:43,000
Power sources in an electric circuit provide electrical energy necessary to initiate the

17
00:00:43,000 --> 00:00:44,000
movement of the electrons.

18
00:00:45,000 --> 00:00:49,000
You have cells, batteries and power supply units and alternators that are examples of

19
00:00:49,000 --> 00:00:50,000
these power supplies.

20
00:00:51,000 --> 00:00:55,000
Conductors transport electrical energy from the power source to the load device.

21
00:00:56,000 --> 00:01:00,000
The load devices receive the electrical energy from the power source and convert it into

22
00:01:00,000 --> 00:01:03,000
other types of useful energy.

23
00:01:03,000 --> 00:01:06,000
And the control devices regulate the circuit.

24
00:01:06,000 --> 00:01:12,000
They can allow or prevent the flow of electric from passing through the circuit.

25
00:01:15,000 --> 00:01:18,000
Finally, you have here the component and symbols table.

26
00:01:18,000 --> 00:01:19,000
This is in your book.

27
00:01:19,000 --> 00:01:24,000
Have a look on them because you have its component, the name, the definition, what

28
00:01:24,000 --> 00:01:32,000
it's doing in the circuit and the electrical symbol that you can take all the electrical

29
00:01:32,000 --> 00:01:34,000
symbols, all of these components.

30
00:01:34,000 --> 00:01:36,000
Go through all of them, read them.

31
00:01:37,000 --> 00:01:42,000
Be careful because some of them are really easy to differentiate but others are different.

32
00:01:42,000 --> 00:01:43,000
For example, inlets.

33
00:01:44,000 --> 00:01:51,000
This component, LEDs, they produce electricity, they produce light but as you can see here

34
00:01:51,000 --> 00:01:52,000
they have two different terminals.

35
00:01:52,000 --> 00:01:57,000
The shorter one is the negative and it should be connected in the electricity kit to the

36
00:01:57,000 --> 00:01:58,000
negative terminal of the battery.

37
00:01:58,000 --> 00:02:02,000
If you connect it in the wrong way, it doesn't produce electricity.

38
00:02:03,000 --> 00:02:05,000
Resistors, that they have these band colours.

39
00:02:06,000 --> 00:02:07,000
This is a potentiometer.

40
00:02:07,000 --> 00:02:12,000
Potentiometer has the same symbol of a resistor and as you can see here with the arrow what

41
00:02:12,000 --> 00:02:21,000
we make in this little round black light right here, you can change the value of the resistor

42
00:02:21,000 --> 00:02:23,000
given two borders.

43
00:02:23,000 --> 00:02:26,000
Another component, the control devices, you know some of them.

44
00:02:26,000 --> 00:02:28,000
This is a one-way switch.

45
00:02:29,000 --> 00:02:30,000
This is a push switch.

46
00:02:31,000 --> 00:02:32,000
We have two different, normally open.

47
00:02:32,000 --> 00:02:38,000
Normally open allows the electrical current when you press them and normally closed, they

48
00:02:38,000 --> 00:02:43,000
stop the current from flowing through one side to the other when you press them.

49
00:02:44,000 --> 00:02:45,000
This is a two-way switch.

50
00:02:45,000 --> 00:02:53,000
You can select one branch of the C-kit when you change the position of this little thing

51
00:02:53,000 --> 00:02:58,000
here and this is also a two-way switch but it controls at the same time two different

52
00:02:58,000 --> 00:03:04,000
C-kits or two different branches of my C-kit.
