1 00:00:00,750 --> 00:00:07,750 Hello, I'm going to do the Compulsory Activity, an ICT activity, Electric Circuits 2 00:00:07,750 --> 00:00:17,750 We have a video that explains how to draw the circuit diagrams of these circuits 3 00:00:17,750 --> 00:00:28,750 And as well we have another video to explain how to measure currents and voltage using this simulator 4 00:00:28,750 --> 00:00:43,750 As this is an Adobe Flash simulator and some people have problems with their operating systems, I am going to do the same but using our traditional simulator 5 00:00:43,750 --> 00:00:50,750 What we have here is a series circuit and a parallel circuit 6 00:00:50,750 --> 00:00:58,390 circuit, we have to measure the voltage drop across L2 in the series circuit here, across 7 00:00:58,390 --> 00:01:07,489 L2, between these two points, B and C, the voltage drop, and as well, in the parallel 8 00:01:07,489 --> 00:01:14,549 circuit, we need to measure the current through L2, the current that goes through this lamp. 9 00:01:14,549 --> 00:01:22,930 Okay, so it says that it is related to paper activity 18 10 00:01:22,930 --> 00:01:26,609 I have here our workbook 11 00:01:26,609 --> 00:01:30,209 And this is the circuit we have to draw 12 00:01:30,209 --> 00:01:34,730 I'm going to use these resistances 13 00:01:34,730 --> 00:01:38,290 Each lamp has this resistance 14 00:01:38,290 --> 00:01:42,069 So I'm going to do this using these values 15 00:01:42,069 --> 00:01:50,069 If you have the same lamps with the same resistance, it doesn't matter 16 00:01:50,069 --> 00:02:02,069 because here the important thing is how to connect the voltmeter and how to connect the ammeter 17 00:02:02,069 --> 00:02:10,069 Here, as you can see, we are measuring the resistance, look, in this circuit 18 00:02:10,069 --> 00:02:22,580 but I'm going to focus on the activity now so we have to go to ICT activities 19 00:02:22,580 --> 00:02:35,409 sorry class activities arms law and this is the activity activity 18 paper 20 00:02:35,409 --> 00:02:54,300 I'm going to draw this circuit, so it's a battery, it's a six volt battery and three 21 00:02:54,300 --> 00:03:15,759 lamps okay this is the battery and one lamp another lamp here and the third one 22 00:03:15,759 --> 00:04:06,479 and the wires and we complete the circuit closing the pathway for the 23 00:04:06,479 --> 00:04:22,480 current to flow okay okay values so current conventional current and we had 10 20 and 30 24 00:04:22,480 --> 00:04:45,360 ohms and the battery is six volts so the battery six volts 10 is good 20 and 30. okay so now we 25 00:04:45,360 --> 00:04:48,360 Now we have the circuits, the same circuits 26 00:04:48,360 --> 00:05:00,360 And it says here, for the series circuit, what we have to do is to measure the voltage drop across L2 27 00:05:00,360 --> 00:05:04,360 Ok, and for that we need a voltmeter 28 00:05:04,360 --> 00:05:12,360 So we can use this voltmeter and connect it across L2, this lamp 29 00:05:12,360 --> 00:05:18,199 This is the positive probe, the positive terminal of the voltmeter 30 00:05:18,759 --> 00:05:21,959 And this is the negative one 31 00:05:23,240 --> 00:05:27,639 That is good, I could use this here as well, but look 32 00:05:28,279 --> 00:05:30,279 First, two volts, ok? 33 00:05:30,519 --> 00:05:34,120 This point and this other point is the same 34 00:05:34,279 --> 00:05:37,319 And this and this is the same, let's see 35 00:05:37,319 --> 00:05:53,100 Ok, maybe here is clearer, and that is what we have, we are measuring the voltage drop across L2
