Hello, I'm going to do the Compulsory Activity, an ICT activity, Electric Circuits 00:00:00
We have a video that explains how to draw the circuit diagrams of these circuits 00:00:07
And as well we have another video to explain how to measure currents and voltage using this simulator 00:00:17
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 00:00:28
What we have here is a series circuit and a parallel circuit 00:00:43
circuit, we have to measure the voltage drop across L2 in the series circuit here, across 00:00:50
L2, between these two points, B and C, the voltage drop, and as well, in the parallel 00:00:58
circuit, we need to measure the current through L2, the current that goes through this lamp. 00:01:07
Okay, so it says that it is related to paper activity 18 00:01:14
I have here our workbook 00:01:22
And this is the circuit we have to draw 00:01:26
I'm going to use these resistances 00:01:30
Each lamp has this resistance 00:01:34
So I'm going to do this using these values 00:01:38
If you have the same lamps with the same resistance, it doesn't matter 00:01:42
because here the important thing is how to connect the voltmeter and how to connect the ammeter 00:01:50
Here, as you can see, we are measuring the resistance, look, in this circuit 00:02:02
but I'm going to focus on the activity now so we have to go to ICT activities 00:02:10
sorry class activities arms law and this is the activity activity 18 paper 00:02:22
I'm going to draw this circuit, so it's a battery, it's a six volt battery and three 00:02:35
lamps okay this is the battery and one lamp another lamp here and the third one 00:02:54
and the wires and we complete the circuit closing the pathway for the 00:03:15
current to flow okay okay values so current conventional current and we had 10 20 and 30 00:04:06
ohms and the battery is six volts so the battery six volts 10 is good 20 and 30. okay so now we 00:04:22
Now we have the circuits, the same circuits 00:04:45
And it says here, for the series circuit, what we have to do is to measure the voltage drop across L2 00:04:48
Ok, and for that we need a voltmeter 00:05:00
So we can use this voltmeter and connect it across L2, this lamp 00:05:04
This is the positive probe, the positive terminal of the voltmeter 00:05:12
And this is the negative one 00:05:18
That is good, I could use this here as well, but look 00:05:23
First, two volts, ok? 00:05:28
This point and this other point is the same 00:05:30
And this and this is the same, let's see 00:05:34
Ok, maybe here is clearer, and that is what we have, we are measuring the voltage drop across L2 00:05:37
