1
00:00:04,339 --> 00:00:12,140
Study in this unit electrical circuit. We have already studied electrical circuits

2
00:00:12,140 --> 00:00:23,660
and in the last video it was a review of what you should know about this field,

3
00:00:23,660 --> 00:00:36,659
but in this year we are going to look forward and we also we are going to do some calculations

4
00:00:36,659 --> 00:00:49,939
on a to do a study need a little bit more deeply so I think it's a good idea that you

5
00:00:49,939 --> 00:01:15,840
you pay attention in this video well what is in what is itself the electrical

6
00:01:15,840 --> 00:01:25,459
everything is electrical because atoms has electrical nature so we can see we

7
00:01:25,459 --> 00:01:37,280
can understand that everything is something electrical as we have already studied in the

8
00:01:37,280 --> 00:02:02,129
So, the loads, the electrical loads, the electrical loads and a current, an electrical current

9
00:02:02,129 --> 00:02:11,849
that in electrical current the charges can move and it is important

10
00:02:11,849 --> 00:02:21,319
because it is important that the charges can come up and if you

11
00:02:21,319 --> 00:02:32,240
want that the electrical charge moves you will need something, a carrier for this

12
00:02:32,240 --> 00:02:47,330
something that can can can be used a a a career and there are mainly two types

13
00:02:47,330 --> 00:02:57,629
one are electrons which are a particle that you can find in the in the awesome

14
00:02:57,629 --> 00:03:11,550
in the in the atom and holes which is in itself when electron

15
00:03:11,550 --> 00:03:29,610
don't exist is something that can be defined with the with no existence of electrons it is

16
00:03:29,610 --> 00:03:41,270
and home both electric electrons and holes are the the main for the main

17
00:03:41,270 --> 00:03:50,509
careers of churches of electrical churches and its movement is movement is

18
00:03:50,509 --> 00:04:05,330
the main reason why the electric circuit exists. So this flow of

19
00:04:05,330 --> 00:04:13,830
electrons or holes through a conductive material is that we usually call

20
00:04:13,830 --> 00:04:26,560
electric current. So it's important to know the electrical magnitudes under

21
00:04:26,560 --> 00:04:36,879
units because it can define what is an electrical circuit. We have

22
00:04:36,879 --> 00:04:49,600
Church which is a matter characteristics and its unit is column. We also have

23
00:04:49,600 --> 00:05:04,980
resistance which is the the opposition of the the materials to this movement of churches we

24
00:05:04,980 --> 00:05:18,660
also have a intensity or current which unit is ampere and it is the quantity of

25
00:05:18,660 --> 00:05:36,259
charge per unit of time voltage which is energy per unit of charge and it's

26
00:05:36,259 --> 00:05:49,379
unit is volt and we also energy electric energy and electric power electric power a can be

27
00:05:49,379 --> 00:06:05,759
calculate by the product of a volt current and energy is the electric power multiplied by time.

28
00:06:05,759 --> 00:06:26,660
the unit to electric power is a value but for electric energy is tuned important also because

29
00:06:26,660 --> 00:06:38,959
a we usually use them to represent the circuits electrical circuits and as we as we already know

30
00:06:38,959 --> 00:06:44,899
in technology the graphical communication is very very important so

31
00:06:44,899 --> 00:06:54,500
symbols are very very important and we we need design circuit using symbols and

32
00:06:54,500 --> 00:07:04,500
and we also need to read these diagrams well.

33
00:07:04,500 --> 00:07:37,129
The cycles are important, well, to know and to calculate something in our, in any, in an electrical cycle, you need the Ohm's law, which is this.

34
00:07:37,129 --> 00:07:50,790
The Young's law shows the relationship between current, resistance and voltage and it's so

35
00:07:50,790 --> 00:07:53,350
important because of this.

36
00:07:53,350 --> 00:08:02,589
So you need to study and to understand this law.

37
00:08:02,589 --> 00:08:22,300
It's something that you can, well, the George Bolt, George Simon Bolt, has come up with

38
00:08:22,300 --> 00:08:29,459
this equation and it's very important in the electric cycles.
