00:00:01.570 --> 00:00:04.230
in line with
2
00:00:05.930 --> 00:00:13.840
better at the
moment than it comes to
3
00:00:15.100 --> 00:00:23.830
throughout
the day to whatever
4
00:00:25.710 --> 00:00:36.860
to whatever it is to us
5
00:00:38.030 --> 00:00:40.550
what interests us already
6
00:00:42.150 --> 00:00:49.270
move on to what
it will be and if
7
00:00:51.490 --> 00:00:59.740
if you haven't
already been to it
8
00:01:01.090 --> 00:01:07.480
seven and passes to four
9
00:01:08.460 --> 00:01:18.500
I do it now I'm not going to if
well if it's not easy what you wrote it
10
00:01:19.190 --> 00:01:31.870
I'm sorry I
don't because I come to
11
00:01:32.720 --> 00:01:42.930
I don't know
again that it's going to
12
00:01:44.620 --> 00:01:59.830
if it's not going to be how
13
00:02:01.410 --> 00:02:13.720
I'm not
going to write it or
14
00:02:16.720 --> 00:02:22.500
going to not go to
15
00:02:23.910 --> 00:02:41.890
imagine
already to the way in
16
00:02:43.070 --> 00:02:46.780
that goes to four
17
00:02:48.310 --> 00:03:00.540
five to four to
four to half a point
18
00:03:02.940 --> 00:03:09.370
a goes to
physics that are within
19
00:03:11.890 --> 00:03:14.360
we're not
going to class here
20
00:03:15.080 --> 00:03:20.270
a a tomorrow to which
21
00:03:21.530 --> 00:03:41.020
will have no house surely
yes early in the morning I will
22
00:03:42.420 --> 00:04:22.870
use it to
23
00:04:28.810 --> 00:04:55.220
he's going to not go to me
24
00:04:58.390 --> 00:05:01.110
come on for forty minutes
25
00:05:02.940 --> 00:05:21.540
walks to wonder to
26
00:05:24.650 --> 00:05:32.450
it goes to when you
27
00:05:33.690 --> 00:05:44.330
it's going to come and
28
00:05:46.090 --> 00:06:43.280
going to ya
va a tengo e a a
29
00:06:45.640 --> 00:06:55.710
a a a is not going to
30
00:06:57.880 --> 00:07:06.210
a and I'm going to
study the tangent on the right
31
00:07:09.010 --> 00:07:09.470
e
32
00:07:12.430 --> 00:07:48.780
to now will not leave
will not escape will not
33
00:07:50.830 --> 00:09:24.180
happens to a a not
if you are going to a
34
00:09:29.730 --> 00:09:49.340
a e of capacitors
35
00:09:52.310 --> 00:09:55.880
you are going to see that it is
a very fast topic with few concepts
36
00:09:57.370 --> 00:10:00.250
you can work it out
37
00:10:01.160 --> 00:10:03.540
in a week you
can work well and
38
00:10:04.990 --> 00:10:10.040
well let's see the
definition of a capacitor work only
39
00:10:10.180 --> 00:10:13.940
the flat capacitor what
happens to it capacitor when we put a
40
00:10:14.340 --> 00:10:16.110
insulating material inside
41
00:10:17.510 --> 00:10:21.750
can be a plastic can be any
material that does not have free electrons
42
00:10:22.580 --> 00:10:27.290
e how to work an association of
capacitors that is an association
43
00:10:27.930 --> 00:10:32.040
to stored energy and
some interesting applications
44
00:10:33.930 --> 00:10:35.730
that we will see to
45
00:10:37.250 --> 00:10:38.140
_ _ EMPTY _ _
46
00:10:41.110 --> 00:10:45.330
a capacitor is always a
pair of conductors with influence
47
00:10:45.330 --> 00:10:46.330
electrostatic
48
00:10:48.470 --> 00:10:51.880
and here we connect a little what
we have worked on the previous topic
49
00:10:52.390 --> 00:10:53.900
when we have two drivers
50
00:10:54.560 --> 00:10:55.980
and total influence
51
00:10:58.580 --> 00:11:02.340
that is to say that the entire
electric field field line of conductor one
52
00:11:02.710 --> 00:11:03.960
arrives at the driver two
53
00:11:05.020 --> 00:11:08.270
that is what happens
because the burden that there is in
54
00:11:08.490 --> 00:11:12.240
the surface are equal
and of opposite sign is valid
55
00:11:12.850 --> 00:11:17.220
good to those two
surfaces with identical load
56
00:11:17.220 --> 00:11:20.640
but contrary sign are
called armor of a capacitor worth
57
00:11:22.020 --> 00:11:24.510
and then
there's a parameter
58
00:11:25.190 --> 00:11:26.240
that characterizes
59
00:11:27.620 --> 00:11:29.630
a capacitor which is
what is called the capacity
60
00:11:30.530 --> 00:11:34.030
which is defined
as the burden we have
61
00:11:34.550 --> 00:11:36.990
in armor in charge q
62
00:11:37.760 --> 00:11:41.790
divided by the difference in
potential between the two conduits
63
00:11:42.770 --> 00:11:47.140
_ _ EMPTY _ _
64
00:11:48.320 --> 00:11:48.870
_ _ EMPTY _ _
65
00:11:51.710 --> 00:11:56.440
this definition
66
00:11:57.670 --> 00:12:03.680
it is an invariable always
invariable in any only dependent capacitor
67
00:12:03.940 --> 00:12:06.440
of the geometry of the
capacitor with which we are working
68
00:12:08.210 --> 00:12:11.220
this depends on
69
00:12:20.660 --> 00:12:25.170
and as it depends only on the
geometry we put cylindrical or flat
70
00:12:25.590 --> 00:12:27.710
because basically
it is always
71
00:12:33.620 --> 00:12:38.510
an invariable worth we can
increase the difference in power
72
00:12:38.660 --> 00:12:40.410
automatically
increase the load
73
00:12:41.160 --> 00:12:45.150
we can decrease the load
automatically will decrease the potential difference
74
00:12:45.350 --> 00:12:48.560
but value is the quotient
always comes out a constant number
75
00:12:48.920 --> 00:12:50.270
which depends
on the geometry
76
00:12:51.140 --> 00:12:53.990
if we do not vary the
geometry of the capacitor start itself
77
00:12:53.990 --> 00:12:56.210
that's what it means
78
00:12:57.770 --> 00:13:00.950
the unit of
measure is the Faradio
79
00:13:04.560 --> 00:13:06.260
Faradio who is a culomb
80
00:13:07.480 --> 00:13:08.870
divided by a volt
81
00:13:10.490 --> 00:13:13.660
what happens that as
you see in practice are used
82
00:13:13.660 --> 00:13:16.300
the derived
nanopharadio units the
83
00:13:17.640 --> 00:13:19.110
microfaradio vale
84
00:13:23.310 --> 00:13:29.130
e in the case of a flat
capacitor you have here drawn
85
00:13:30.090 --> 00:13:32.550
it's a case of how we've
talked about influence before
86
00:13:32.550 --> 00:13:36.450
total electrostatic as
long as the separation distance
87
00:13:36.760 --> 00:13:40.670
between plate armor
is very small compared to
88
00:13:40.670 --> 00:13:43.030
the dimensions of
the plates compared
89
00:13:43.570 --> 00:13:47.020
with the
sides of the surface
90
00:13:48.460 --> 00:13:52.970
if it 's very small, it' s
theoretically the same thing as approaching.
91
00:13:52.970 --> 00:13:54.670
to the ideal
case of infinite plates
92
00:13:55.750 --> 00:13:58.860
then the total influence of
the electric field always goes
93
00:13:59.070 --> 00:14:01.130
from positive charge
to negative we will go
94
00:14:02.470 --> 00:14:06.130
well then let's as I
said before we focus alone
95
00:14:06.130 --> 00:14:07.170
in the capacitor
96
00:14:11.990 --> 00:14:14.650
and
97
00:14:15.480 --> 00:14:21.700
and
98
00:14:26.300 --> 00:14:29.730
you have it
there perfectly drawn
99
00:14:29.730 --> 00:14:34.610
let's learn how the capacitor
capacity is calculated if we have
100
00:14:34.980 --> 00:14:37.790
two flat plates
101
00:14:41.590 --> 00:14:43.640
e and
102
00:14:45.060 --> 00:14:50.410
e parallels are
connected to a source
103
00:14:52.240 --> 00:14:53.300
to a battery
104
00:14:54.390 --> 00:14:57.780
and that battery what it does
is keep the potential difference
105
00:14:58.120 --> 00:14:59.760
between driver
one and the cont
