1 00:00:00,560 --> 00:00:08,560 Ok, now we are going to finish this activity by drawing the parallel circuit 2 00:00:09,560 --> 00:00:16,559 This is the series circuit and this one is the parallel circuit 3 00:00:17,559 --> 00:00:26,559 And we have a 5V battery and 3 lamps, each lamp is 10, 25 and 5 ohms 4 00:00:26,559 --> 00:00:34,560 So first we need to create, we need to build the circuit 5 00:00:34,560 --> 00:00:42,450 The battery and the three lamps 6 00:00:42,450 --> 00:01:01,409 One, two and the third one 7 00:01:01,409 --> 00:01:18,599 it's a parallel circuit so the wires has to be in parallel 8 00:01:18,599 --> 00:01:38,480 among them okay that would be here hey and the same for these other parts of 9 00:01:38,480 --> 00:01:55,969 the circuit. That is what I am trying to remember. This wire, this wire and this wire are more or less in parallel 10 00:01:55,969 --> 00:02:15,449 It is the same word but different meaning. And we need to close the circuit so current flows 11 00:02:15,449 --> 00:02:23,449 through each branch, this branch, this another branch, this another branch 12 00:02:23,449 --> 00:02:32,449 ok, what we have to do in this part is to measure the current through L2 13 00:02:32,449 --> 00:02:41,449 so we can do, the easiest way of doing this is using this ammeter 14 00:02:41,449 --> 00:02:59,449 It's a virtual ammeter, so we don't need to connect it, but first we have to write the proper values of each component 15 00:02:59,449 --> 00:03:07,449 and it's 5 volts and then 10, 25 and 5 16 00:03:08,449 --> 00:03:13,449 5 volts the battery 17 00:03:14,449 --> 00:03:21,039 5, I don't remember 18 00:03:21,039 --> 00:03:24,039 10, 25 and 5 19 00:03:24,039 --> 00:03:27,550 this is 10 20 00:03:27,550 --> 00:03:47,840 25 and 5 21 00:03:47,840 --> 00:03:59,099 This is the circuit, this is our virtual ammeter, and to measure the current through this lamp, L2, we only have to do this 22 00:03:59,099 --> 00:04:03,919 And it says 0.20 amps 23 00:04:03,919 --> 00:04:11,960 This is the same as it says here in the paper activity 24 00:04:11,960 --> 00:04:16,360 0.2 amps 25 00:04:16,360 --> 00:04:31,360 But I prefer to use this ammeter, this is more or less the real ammeter, and so we need to connect the ammeter in the circuit 26 00:04:31,360 --> 00:04:38,360 That is good, if you do this, that is good, but I am going to use the real ammeter 27 00:04:38,360 --> 00:04:48,180 okay for that we need to open the circuit this is the ammeter so we need to connect the ammeter 28 00:04:48,180 --> 00:04:57,620 before the lamp or after the lamp as I have more space here I'm going to use this after the lamp 29 00:04:57,620 --> 00:05:11,620 Ok, I'm going to eliminate this and now here the ammeter 30 00:05:11,620 --> 00:05:29,850 So the current has to enter the ammeter, goes inside the ammeter and continues, comes out of the ammeter 31 00:05:29,850 --> 00:05:33,449 Here and there 32 00:05:33,449 --> 00:05:36,350 This is the real thing 33 00:05:36,350 --> 00:05:43,350 So, as you can see, the current, of course, is exactly the same, 0.20 amps 34 00:05:43,350 --> 00:05:48,310 And this is the way we can measure current in a circuit 35 00:05:48,310 --> 00:05:50,910 And that's all. Thank you
