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
that in electrical current the charges can move and it is important 00:02:02
because it is important that the charges can come up and if you 00:02:11
want that the electrical charge moves you will need something, a carrier for this 00:02:21
something that can can can be used a a a career and there are mainly two types 00:02:32
one are electrons which are a particle that you can find in the in the awesome 00:02:47
in the in the atom and holes which is in itself when electron 00:02:57
don't exist is something that can be defined with the with no existence of electrons it is 00:03:11
and home both electric electrons and holes are the the main for the main 00:03:29
careers of churches of electrical churches and its movement is movement is 00:03:41
the main reason why the electric circuit exists. So this flow of 00:03:50
electrons or holes through a conductive material is that we usually call 00:04:05
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 to this movement of churches we 00:04:49
also have a intensity or current which unit is ampere and it is the quantity of 00:05:04
charge per unit of time voltage which is energy per unit of charge and it's 00:05:18
unit is volt and we also energy electric energy and electric power electric power a can be 00:05:36
calculate by the product of a volt current and energy is the electric power multiplied by time. 00:05:49
the unit to electric power is a value but for electric energy is tuned important also because 00:06:05
a we usually use them to represent the circuits electrical circuits and as we as we already know 00:06:26
in technology the graphical communication is very very important so 00:06:38
symbols are very very important and we we need design circuit using symbols and 00:06:44
and we also need to read these diagrams well. 00:06:54
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. 00:07:04
The Young's law shows the relationship between current, resistance and voltage and it's so 00:07:37
important because of this. 00:07:50
So you need to study and to understand this law. 00:07:53
It's something that you can, well, the George Bolt, George Simon Bolt, has come up with 00:08:02
this equation and it's very important in the electric cycles. 00:08:22
