Hello! Well, it's a good tool which can help you to design and to dimension some electrical circuits to be crocodile eclipse, which is a program of simulation of circuits.
00:00:06
I think you have already used it in the first episode, but now we are going to study how to use in order to use it to do and resolve some examples and some exercises.
00:00:31
So the first thing you should do is open Crocodile Eclipse, it can be opened in pictures, sometimes
00:00:55
it is better when you are beginning to learn symbols, electrical symbols, but I think for
00:01:05
all of us it is better to start it in symbols directly.
00:01:17
So as you see, there are a lot of categories of elements of circuits, firstly the batteries.
00:01:25
This symbol is for a current battery.
00:01:43
So we choose this symbol, don't care about the value because we can change at the end.
00:01:53
And after the battery, the other important element is to control, here you can see a
00:02:08
lot of switches so switches and other kind of things and this is one of the of the most
00:02:17
most simple to to use it you also have wheelers and other kind of switches
00:02:30
And now you also have resistance, boob, boozers or even gears and so on.
00:02:39
So we are going to start with something very simple which can be just only a resistance
00:02:59
like that, when you have chosen the parts of our circuit we join the part with the cable
00:03:05
And now we can change the values, for example, you can change the value, 5 volts, or this
00:03:30
other value.
00:03:42
Well, this circuit is good, but obviously we want to calculate and measure the magnitudes
00:03:44
of the circuit there are three which are voltage resistance and the other one obviously is current
00:03:58
so to calculate the current we can use an amperimeter which is this and if you want to
00:04:10
to use the amperimeter to calculate you need insert it in the circuit because
00:04:23
you should connect it in serial so you should insert in the circuit and
00:04:30
now you obviously has the value of the current if you change the value of the
00:04:41
resistance, just 1k, 1k for example, the value of recurring increases, as you can
00:04:58
see, because it's the Ohm's law. Well, but we also use this kind of circuit to
00:05:16
calculate and to resolve our problems in
00:05:29
series connection and in parallel
00:05:33
connection for example I can connect
00:05:35
other resistance which value can be 3
00:05:39
for example and I'm going to connect it
00:05:46
firstly in parallel and secondly in
00:05:52
So firstly, this amperimeter shows us the value of the total current
00:06:06
We also can use a cocodile to know the value of the current in each resistance
00:06:18
So now, as you can see, the sum of 5 mA and 1.67 mA is 6.67
00:06:28
and as the circuit, the connection, is in parallel, the voltage in each resistance is the same, 5 volts
00:07:33
So we have solved a problem of the parallel connection just by using this program and without any calculation
00:07:44
Now, if we want to do more or less the same but in a serial connection, we should connect
00:08:00
the two resistances in this kind of connection, 3 and 1.
00:08:14
In this case, the current is the same for both and its value is 1.25, but the voltage
00:08:35
is the sum of the voltage in each resistance and to know it is very easy because we just
00:08:56
can use a voltimeter and connect the voltimeter in parallel, which is resistance
00:09:06
And now we can see that the sum of 125 and 375
00:09:15
