1 00:00:01,459 --> 00:00:08,099 Hi, today we are going to learn how to use the online simulator called Tinkercad. 2 00:00:08,099 --> 00:00:16,500 We are going to learn how to login, how to create circuits or 3D designs. We are going to study it 3 00:00:16,500 --> 00:00:23,699 later in some months or weeks, I don't know, maybe months. And we are going to learn how to create 4 00:00:23,699 --> 00:00:31,059 and as i said before and how to share these circuits with me and today in this exercise 5 00:00:31,059 --> 00:00:36,100 we are going to learn also how to measure some magnitudes in the circuit okay the first thing 6 00:00:36,100 --> 00:00:44,020 we need to to know is that the Tinkercad simulator is here in www.tinkercad.com 7 00:00:44,579 --> 00:00:50,740 it's a web page you don't need to install anything just go to this web page and then 8 00:00:50,740 --> 00:00:58,740 The moment you go here, we are going to click on login and then because we are students we are going to click here 9 00:00:58,740 --> 00:01:04,739 Si eres estudiante, únete a la clase, click on it. And the first thing you will need is the code of the classroom. 10 00:01:04,739 --> 00:01:09,739 I will give it to you. For instance, I have created this classroom for this example. 11 00:01:09,739 --> 00:01:13,739 I want to copy the code and paste it because I don't know it by heart. 12 00:01:13,739 --> 00:01:20,739 And now you need a second thing, you need a nickname, ok, you need a second apple. 13 00:01:20,739 --> 00:01:26,739 We click on it, you need to enter the nickname. The nickname I will give it to you also. 14 00:01:26,739 --> 00:01:35,879 I've created this one just for this example, I copy and paste it, and now I'm in. 15 00:01:35,879 --> 00:01:42,879 And the moment you are in, as you can see here in my Tinkercad webpage, you will find different possibilities. 16 00:01:42,879 --> 00:01:49,640 One of them is the 3D design blocks, for the moment we are not going to use them, maybe 17 00:01:49,640 --> 00:01:52,180 in the future, but not for the moment. 18 00:01:52,180 --> 00:02:05,680 Click on circuits here, and now here I have a lot of different circuits because I have 19 00:02:05,680 --> 00:02:16,520 already used this website a lot of times, but your web page will be empty, there will 20 00:02:16,520 --> 00:02:23,699 be no circuit, so what you have to do, you will click on create new circuit and here 21 00:02:23,699 --> 00:02:36,039 you will create your own circuit, okay. 22 00:02:36,039 --> 00:02:47,520 Here on the right, this window is a kind of new, a piece of news, okay, we can close it. 23 00:02:47,520 --> 00:02:52,800 Here on the right there is the library and we are going to select all because we want 24 00:02:52,800 --> 00:02:58,500 all of them and we are going to use different components for example for 25 00:02:58,500 --> 00:03:04,740 example for example I'm looking for a power source I want to refer in Spanish 26 00:03:04,740 --> 00:03:14,599 Fuente, it doesn't appear so I will look slide in the slide in them the one I'm 27 00:03:14,599 --> 00:03:20,860 going to use is like a source of energy is going to be is going to be here 28 00:03:20,860 --> 00:03:28,139 suministro de energía, okay? This is a kind of battery, okay? I also want some resistors, 29 00:03:28,139 --> 00:03:33,979 they are here, I want to use them, three of them, I click and drag, click and drag, 30 00:03:35,580 --> 00:03:40,939 and the values for them will be, I click on the first one and I want five ohms, 31 00:03:41,979 --> 00:03:50,699 and I change, instead of using kilo ohms, I will use ohms. Next one will be a 10 ohms one. 32 00:03:50,860 --> 00:04:02,620 10 ohms, 10 ohms, and this one will be a 10 ohms one, two, 10 ohms, okay, now I have three 33 00:04:02,620 --> 00:04:11,000 of them, this way, this way, this way, and I will rotate this one, because I want this 34 00:04:11,000 --> 00:04:19,160 circuit, the one we have, the example we, I used in class, so I'm going to create this 35 00:04:19,160 --> 00:04:30,589 circuit if I click here here this one another wire from this position I'm 36 00:04:30,589 --> 00:04:39,819 sorry it's not that easy as it looks but it's not very difficult okay here here 37 00:04:39,819 --> 00:04:46,560 here and this one will be this wire will be from here to here because these two 38 00:04:46,560 --> 00:04:54,079 ones are the connectors of the battery here so now I have this circuit 39 00:04:54,079 --> 00:04:57,220 is the one we have used in the classroom. 40 00:04:58,660 --> 00:05:00,500 Does it work? Yes, let's have a look. 41 00:05:01,000 --> 00:05:06,079 If I click on the power of source, I will apply 5 volts voltage. 42 00:05:06,540 --> 00:05:09,819 Don't worry about the current. This is not the current you are using. 43 00:05:09,939 --> 00:05:15,060 This is the maximum current it will supply. 44 00:05:15,800 --> 00:05:18,180 So, how can I simulate the circuit? 45 00:05:18,319 --> 00:05:22,740 Just click in here, Iniciar Simulación, and the circuit is working. 46 00:05:22,740 --> 00:05:27,120 this is the voltage I'm applying and this is the intensity that is crossing 47 00:05:27,120 --> 00:05:32,980 the power source so we don't need to measure this intensity because the 48 00:05:32,980 --> 00:05:43,959 source of energy is showing this to us anyway okay how to before before 49 00:05:43,959 --> 00:05:47,879 sharing it with me we are going to measure things because this exercise is 50 00:05:47,879 --> 00:05:55,759 about measuring okay I will use the multimeter if we click and drag and we 51 00:05:55,759 --> 00:06:03,300 move down here I have a multimeter I can measure voltage intensity resistance I 52 00:06:03,300 --> 00:06:10,300 want to use it to measure voltage so I will I'm sorry I will measure the 53 00:06:10,300 --> 00:06:19,199 voltage of this resistor and if I start simulation again two and a half volts 54 00:06:19,199 --> 00:06:28,980 the voltage here. I stop the simulation, I erase the wire, I erase the wire, I rotate 55 00:06:28,980 --> 00:06:38,279 this one here, and I will measure voltage again. Here and here. I will measure the 56 00:06:38,279 --> 00:06:44,819 voltage again. And again, two and a half volts. The voltage is the same just 57 00:06:44,819 --> 00:06:49,139 because of the values of the of the resistors if I change one of them for 58 00:06:49,139 --> 00:06:53,339 instance I will stop the simulation and I will change this one instead of being 59 00:06:53,339 --> 00:07:00,300 five if it will be ten and now everything changes this one is not two 60 00:07:00,300 --> 00:07:05,220 and a half anymore I'm providing five volts but here the intensity is different 61 00:07:05,220 --> 00:07:13,560 okay anyway I will go back to five five ohms here okay fine perfect and if I 62 00:07:13,560 --> 00:07:19,779 measure again, again two and a half. Okay, so everything works as expected. Okay, I 63 00:07:19,779 --> 00:07:23,740 have measured, I know the voltage here, I have measured the voltage here, and I 64 00:07:23,740 --> 00:07:37,689 know the voltage for these two resistors. What if I measure, I want to erase this 65 00:07:37,689 --> 00:07:46,389 one, click on erase, okay, I don't know what happens here, oh no, it wasn't selected, now it was 66 00:07:46,389 --> 00:07:50,569 selected okay I will measure now I want to measure the intensity that is crossing 67 00:07:50,569 --> 00:08:00,129 this resistor how can I do it okay I will connect it this way so now the 68 00:08:00,129 --> 00:08:05,449 multimeter is connected in series with this resist intensity and every electron 69 00:08:05,449 --> 00:08:11,529 that crosses this resistor will cross the ammeter and I won't I won't use it 70 00:08:11,529 --> 00:08:16,829 as an ammeter okay don't forget to change this the way it works if I click 71 00:08:16,829 --> 00:08:25,310 again on Iniciar value, Iniciar Simulación, again I'm sorry, now it's measuring 250 mA, 72 00:08:25,310 --> 00:08:34,269 okay? Okay, so again I will erase these wires and I will connect this one the same way as 73 00:08:34,269 --> 00:08:38,590 it was connected before. If I won't connect it, well anyway, I don't have to measure this 74 00:08:38,590 --> 00:08:48,029 this wire because here if I have a 500mA I will have 500mA here so the one I want to 75 00:08:48,029 --> 00:08:59,070 measure is this one so what can I do I will erase this wire and this wire and I will place 76 00:08:59,070 --> 00:09:08,549 the ammeter here this way and I will connect it this way and this one is going to be connected 77 00:09:08,549 --> 00:09:17,789 to this one. So it's exactly the same circuit but every electron that 78 00:09:17,789 --> 00:09:23,190 crosses this one will cross the ammeter and it will be measured this way. If I 79 00:09:23,190 --> 00:09:28,990 click Iniciar Simulación and again 250 amperes because these two resistors both 80 00:09:28,990 --> 00:09:34,049 of them have the same resistance. If I change one 81 00:09:34,049 --> 00:09:39,690 of them, for instance this one, you will see that the intensity will change in the 82 00:09:39,690 --> 00:09:47,809 first simulation and now it's different, okay? So now the exercise. You will create 83 00:09:47,809 --> 00:09:56,299 a circuit like this one. Remove the wires to make it easier to show it to 84 00:09:56,299 --> 00:10:05,379 you. You will create a circuit like this one and you will measure intensity here, 85 00:10:05,379 --> 00:10:11,919 intensity here and voltage here and for the two of them so you will need you 86 00:10:11,919 --> 00:10:19,379 will need one two three and four multimeters two of them to measure 87 00:10:19,379 --> 00:10:26,139 intensity here and here and two of them to measure voltage for this one and for 88 00:10:26,139 --> 00:10:31,379 these two ones okay four ammeters and two voltmeters you will place them in the 89 00:10:31,379 --> 00:10:39,039 circuit you already have seen how to place them okay okay you now you know 90 00:10:39,039 --> 00:10:42,340 how to do it but the problem is you don't know how to and share it with me 91 00:10:42,340 --> 00:10:50,620 so if you want to share it with me you can share it with me just sending this 92 00:10:50,620 --> 00:10:58,919 URL address to me okay this is the one you have to copy and paste okay the 93 00:10:58,919 --> 00:11:05,940 editor is not compulsory, sorry, the editor part is not compulsory but anyway if you 94 00:11:05,940 --> 00:11:11,279 paste it is fine anyway. This is the link and the one you have to copy. The moment 95 00:11:11,279 --> 00:11:17,879 you open the circuit, copy, right click, copy and then you paste it in the 96 00:11:17,879 --> 00:11:23,299 task. This way I will be able to have a look at it. Don't forget to use the four 97 00:11:23,299 --> 00:11:28,440 multimeters, don't forget to place them properly, okay? The same way I have 98 00:11:28,440 --> 00:11:37,279 already done that in the exercise okay so and that's all good luck
