00:00:00,000 --> 00:00:07,419
Hello and welcome to another natural science video. Today the two types we have to learn

2
00:00:07,419 --> 00:00:14,560
about electricity, static and current electricity. Here we go. Static electricity. Static electricity

3
00:00:14,560 --> 00:00:21,260
gathers in one place, se acumula, stays in one place. Examples that you know, a balloon,

4
00:00:21,859 --> 00:00:27,640
when you touch a metal, or when you comb your hair. I really hate when this happens, you know.

5
00:00:27,640 --> 00:00:46,100
Okay. Static electricity. Look at the example that you have in your book. It's on page 70. Look, this is how it happens. Static electricity occurs when there is an imbalance, a disequilibrio, of positive and negative charges between two electrical scintillators.

6
00:00:46,100 --> 00:00:50,100
Electrons, in this case from the boy you get in the picture,

7
00:00:50,100 --> 00:00:55,100
rub off onto the floor, onto the carpet, and he is positively charged.

8
00:00:55,100 --> 00:01:01,100
Opposite charges, remember they attract the electrons of a negatively charged object,

9
00:01:01,100 --> 00:01:04,099
are attracted to a positively charged object.

10
00:01:04,099 --> 00:01:09,099
When lots of electrons move at the same time you may see the spark

11
00:01:09,099 --> 00:01:15,099
or you feel like a small shock, like when you touch the metal door in this case.

12
00:01:15,099 --> 00:01:21,260
this case now another or the most important example of static electricity in nature

13
00:01:22,299 --> 00:01:28,859
are lightnings look at the picture lining how they happen look rain clouds they move

14
00:01:29,500 --> 00:01:37,340
very fast okay you are ready for a storm and water air and ice particles inside the

15
00:01:38,140 --> 00:01:44,700
cloud they rub against each other and they create the static electrical charge finally

16
00:01:44,700 --> 00:01:51,420
when the charge is big enough clouds release the energy and which we can see as as a light

17
00:01:52,459 --> 00:01:59,819
the other term current electricity it flows it moves the electricity you have at home

18
00:01:59,819 --> 00:02:07,659
okay electrons pass quickly from one atom to another within certain materials here it's

19
00:02:07,659 --> 00:02:12,939
important that we distinguish this type of materials because we got conductors and insulators

20
00:02:12,939 --> 00:02:19,419
look at them for example silver gold copper steel and sea water they are good conductors or

21
00:02:19,419 --> 00:02:25,979
insulators they are very good conductors good electrical conductors like wires and other metal

22
00:02:25,979 --> 00:02:31,419
objects allow electricity to travel through them easily okay be careful especially with water you

23
00:02:31,419 --> 00:02:38,219
know this then rubber glass oil a diamond wood which when it's dry and since they're getting

24
00:02:38,219 --> 00:02:44,780
water they are electrical insulators rubber plastic woods do not allow electricity to pass

25
00:02:44,780 --> 00:02:51,099
through them finally look at this example the electrical circuits this is the electricity you

26
00:02:51,099 --> 00:02:57,120
get at home an electrical circuit allows electrons to flow through a path we get the wires those

27
00:02:57,120 --> 00:03:02,199
cables they conduct the electricity okay then the power source that provides the electrical energy

28
00:03:02,199 --> 00:03:09,960
for example a battery, okay, una pila, or then you need the switch. The switch opens and closes the

29
00:03:09,960 --> 00:03:15,560
circuits and you can stop the flow of electricity when you turn on or you turn off the lights at

30
00:03:15,560 --> 00:03:23,000
home. And finally a resistor. The resistor, una resistencia, is the object that transforms the

31
00:03:23,000 --> 00:03:28,280
electricity into another form of energy. For example the light bulb is a resistor and it

32
00:03:28,280 --> 00:03:34,280
it transforms electricity into lights this is its static and current

33
00:03:34,280 --> 00:03:38,840
electricity I hope you understand if not you know you can ask and see you

34
00:03:38,840 --> 00:03:42,460
tomorrow all right goodbye
