1 00:00:00,420 --> 00:00:08,250 Hello and welcome to this annual us on which I'll explain to you how to dust out an inductor uh basically 2 00:00:08,260 --> 00:00:10,020 inductor is a coil. 3 00:00:10,080 --> 00:00:12,120 And here we have a Transformer. 4 00:00:12,230 --> 00:00:15,280 It has a Primary coil. 5 00:00:15,360 --> 00:00:22,590 The second recall so we can use these two coils to demonstrate inductor government thing. 6 00:00:22,620 --> 00:00:30,900 So it's really easy to use us need to bring your digital multimeter and apply these tools to the com 7 00:00:30,990 --> 00:00:40,350 and the Volts on the road and her seeding as you can see here the read on the com the red and the Volt 8 00:00:40,390 --> 00:00:44,270 on the old Hertz and the Black is on the cone. 9 00:00:44,340 --> 00:00:57,240 NOW MOVE THIS DIAL to the diode or the um let's say sound Bazar or connectivity uh pattern and make 10 00:00:57,240 --> 00:01:02,750 sure that it's working by simply destroying this as you can see it's working. 11 00:01:02,880 --> 00:01:17,310 Now if you test the binary code it has a very high resistance so it won't display or it won't show connectivity 12 00:01:17,310 --> 00:01:27,780 it will just display that resistance value as you can see we have like a hundred a hundred on resistor 13 00:01:29,760 --> 00:01:30,740 or resistance. 14 00:01:30,950 --> 00:01:31,400 Okay. 15 00:01:33,280 --> 00:01:34,810 One all. 16 00:01:35,300 --> 00:01:38,300 Now the primary distance as you will is it is usually high. 17 00:01:38,420 --> 00:01:42,640 So as you can see here we have one hundred home one hundred on resistor 18 00:01:47,060 --> 00:01:51,110 while the second the resistance is very small very small. 19 00:01:51,110 --> 00:02:00,650 So it's this is because it's taking like 220 volt AC and the biomedical coil and it gives only 6 0 6 20 00:02:00,740 --> 00:02:02,660 volt on the second record. 21 00:02:02,660 --> 00:02:11,600 So this is a center that we have the black wire and we have to blues When we connect these two we will 22 00:02:11,600 --> 00:02:20,750 find half the resistance of the second recall and you can see that using the connectivity test you can 23 00:02:20,750 --> 00:02:27,830 test this out okay media as you can see. 24 00:02:28,430 --> 00:02:31,780 This means that the second the call is working. 25 00:02:31,820 --> 00:02:37,490 Now is this the other one. 26 00:02:37,770 --> 00:02:42,330 Again it's this sound. 27 00:02:42,330 --> 00:02:44,970 This means that this is all connected. 28 00:02:45,450 --> 00:02:51,780 Now most likely when you're just an inductor if it didn't show connectivity or resistance a small resistance 29 00:02:52,080 --> 00:02:57,930 this means that there is a cut in it or there's a problem with that inductor and you have to replace 30 00:02:57,930 --> 00:02:59,020 it. 31 00:02:59,070 --> 00:03:01,350 So there is two types of this for the inductor. 32 00:03:01,380 --> 00:03:03,340 The first one is the connectivity test. 33 00:03:03,480 --> 00:03:06,200 The second one is that a distance test. 34 00:03:06,300 --> 00:03:11,530 So let's test using that as a stance we can match up the resistance. 35 00:03:11,550 --> 00:03:13,460 So this is a sense of type. 36 00:03:13,460 --> 00:03:19,140 So the same resistance must appear on the black and blue on the black on this one. 37 00:03:19,140 --> 00:03:24,480 So the first blue whale will give us that resistance with the black wire which is the very same distance 38 00:03:24,510 --> 00:03:29,100 as between this black white and blue wire here. 39 00:03:29,910 --> 00:03:34,580 So let's test the first resistance OK. 40 00:03:34,590 --> 00:03:36,220 As you can see we have light. 41 00:03:36,210 --> 00:03:42,510 Point eight or point five on the distance on the LCD. 42 00:03:43,170 --> 00:03:49,570 Now we must get our other point five between these two. 43 00:03:49,700 --> 00:03:55,770 Let me just say again point five point four. 44 00:03:55,850 --> 00:04:00,170 So the total distance between the two blue whales will be the sum of these two the distance which is 45 00:04:00,740 --> 00:04:03,620 basically one arm or buoyant clearly 46 00:04:06,690 --> 00:04:09,350 they just fixed this to the table. 47 00:04:10,390 --> 00:04:10,910 OK. 48 00:04:10,920 --> 00:04:13,280 As you can see point eight point seven 49 00:04:16,880 --> 00:04:21,930 and this is the sum of the total distance that we just measure. 50 00:04:22,040 --> 00:04:23,990 This is for the second recall. 51 00:04:23,990 --> 00:04:29,710 It's a very long distance around one arm while the primal core has a very high resistance. 52 00:04:29,750 --> 00:04:43,220 So we put these two this one if you check the LCD you can see that we'll have around 100 ohm OK. 53 00:04:43,240 --> 00:04:51,630 Seventy seven ohm which is like seventy seven times larger than the secondary coil resistance. 54 00:04:51,640 --> 00:04:55,820 So this is how to test the conductance of a coil. 55 00:04:56,050 --> 00:05:03,250 And if it's connected or not if it has a problem or not by testing using the connectivity test here 56 00:05:03,760 --> 00:05:12,160 or using the form test here goes a core it is basically a way of inductor is basically a wire that has 57 00:05:12,160 --> 00:05:17,740 a resistance that you can measure for sure there is other specialized devices for measuring conductance 58 00:05:17,920 --> 00:05:24,310 and it gives you the conductance value not an arm or connectivity gives you the very same conductance 59 00:05:24,310 --> 00:05:31,230 value but we are using this symbol digital multimeter to start out this thing cause buying conductance 60 00:05:31,270 --> 00:05:33,850 digital multimeter would cost you a lot. 61 00:05:34,150 --> 00:05:42,220 So using this symbol device very cheap device you can test conductance using interconnectivity or the 62 00:05:42,340 --> 00:05:48,310 resistance this these other to test you can use to measure conductors if you have any question regarding 63 00:05:48,310 --> 00:05:48,670 this. 64 00:05:48,670 --> 00:05:51,540 You can ask in the currently aboard I'm here to help you. 65 00:05:51,610 --> 00:05:52,660 Thanks for watching. 66 00:05:52,660 --> 00:05:54,970 This is educational engineering team.
