Study in this unit electrical circuit. We have already studied electrical circuits
00:00:04
and in the last video it was a review of what you should know about this field,
00:00:12
but in this year we are going to look forward and we also we are going to do some calculations
00:00:23
on a to do a study need a little bit more deeply so I think it's a good idea that you
00:00:36
you pay attention in this video well what is in what is itself the electrical
00:00:49
everything is electrical because atoms has electrical nature so we can see we
00:01:15
can understand that everything is something electrical as we have already studied in the
00:01:25
So, the loads, the electrical loads, the electrical loads and a current, an electrical current
00:01:37
is that in electrical current the charges can move.
00:02:02
And it is important because it is important that the churches can come up.
00:02:10
And if you want that the electric car church moves, you will need something, a carrier
00:02:19
for this, something that can be used as a carrier.
00:02:31
There are mainly two types, one are electrons, which are a particle that you can find in
00:02:43
in the atom and holes which is in itself when electron don't exist, is something that can
00:02:56
be defined with no existence of electrons, it is a hole. Both electrons and holes are
00:03:20
the main carriers of churches, of electrical churches, and its movement
00:03:38
is movement is the main the main reason why the electric circuit exists so this
00:03:48
flow of electrons or holes through a conductive material is that we usually
00:04:04
call electric current so it's important to know the electrical magnitudes under
00:04:13
units because it can define what is an electrical circuit. We have
00:04:26
Church which is a matter characteristics and its unit is column. We also have
00:04:36
resistance which is the the opposition of the the materials a to to this
00:04:49
movement of churches we also have a intensity or current which unit is
00:05:00
ampere and it is the quantity of charge per unit of time. Voltage which is
00:05:11
energy per unit of charge and its unit is volt and we also energy, electric
00:05:28
energy and electric power. Electric power can be calculated by the product of a volt
00:05:42
current and energy is the electric power multiplied by time. The unit of electric
00:05:54
power is a battery but for electric energy is tuned very important also because we
00:06:10
usually use them to represent the circuits electrical circuits and as we
00:06:28
as we already know in technology the graphical communication is very very
00:06:36
important. So, symbols are very very important and we need to design
00:06:43
circuits using symbols and we also need to read these diagrams well. The
00:06:52
cycles are important well to know and to calculate something in our cell in any
00:07:12
in an electrical cycle you need the Ohm's law which is this the Ohm's law
00:07:28
and shows the relationship between a current resistance and voltage and it's
00:07:38
so important because of this so you you need to study and to understand this
00:07:50
this law. It's something that you can, well, George Bolt, George Simon Bolt has come up
00:07:58
with this equation and it's very important in the electric cycles.
