1 00:00:00,210 --> 00:00:05,250 Hello and welcome to this annual list one which I will teach you how to measure current measuring and 2 00:00:05,250 --> 00:00:12,390 current is uh a little bit harder than measuring voltage because there is uh two ranges in the amber 3 00:00:12,510 --> 00:00:21,060 and the umber range so you don't want to confuse these two because this might damage your digital multimeter. 4 00:00:21,660 --> 00:00:28,290 So when you are measuring if you are measuring small you use this one if you are not sure use this one 5 00:00:28,670 --> 00:00:30,190 because it can measure up to arm. 6 00:00:30,510 --> 00:00:38,210 But if you are higher than an arm you shouldn't use this one you should buy a watch that has such specifications. 7 00:00:38,370 --> 00:00:44,990 Now in order to make that count you need to move the dial here as you can see we have from 20 million 8 00:00:45,030 --> 00:00:50,890 to 10 AC and from 20 million to 10 DC. 9 00:00:51,060 --> 00:01:02,590 So this start by stating how to measure car in order to measure confidence circuits you need to do short. 10 00:01:02,880 --> 00:01:05,010 So you need to cut the circuit. 11 00:01:05,100 --> 00:01:16,800 Let's say that we have a nine volt battery was terminal and we have a lead resistor and LEDs and around 12 00:01:18,300 --> 00:01:25,240 this lead will turn on if we want to measure how much current is withdrawn in this circuit. 13 00:01:25,270 --> 00:01:27,510 We need to break this circuit. 14 00:01:27,750 --> 00:01:29,530 So now it would become like this 15 00:01:34,460 --> 00:01:35,740 and this. 16 00:01:36,060 --> 00:01:40,230 These are the two blobs of the digital multimeter. 17 00:01:40,230 --> 00:01:45,760 We must add them in series with the circuit so that we can measure the current. 18 00:01:45,780 --> 00:01:53,940 Now the same thing apply to as you can see this is a this evolved the same thing apply for AC if you 19 00:01:53,940 --> 00:02:02,040 want to measure current that goes through let's say at 100 to 120 volt AC plug. 20 00:02:02,430 --> 00:02:07,380 Let's say that this is the AC plug you need to go to Little multimeter. 21 00:02:07,380 --> 00:02:11,670 Then let's say that this is a light bulb. 22 00:02:11,670 --> 00:02:13,950 This is the line and this is done. 23 00:02:14,190 --> 00:02:21,750 The neutron will be connected directly while the line all must go through the digital multimeter using 24 00:02:21,750 --> 00:02:22,740 these two blobs. 25 00:02:22,890 --> 00:02:36,380 In order for four to measure this that lamp consumes I will show you how to do it for the D.C. Circuit. 26 00:02:36,450 --> 00:02:38,460 And the same thing applies for the AC circuit. 27 00:02:38,460 --> 00:02:40,010 You need to cut the circuit. 28 00:02:40,150 --> 00:02:44,010 Cut the way out and let it pass through that digital multimeter. 29 00:02:44,010 --> 00:02:50,500 Then you can simply see the results on the icy display from the watch. 30 00:02:50,500 --> 00:02:53,200 Now let's do this in action. 31 00:02:53,310 --> 00:02:58,720 I want to enjoy this Volt saw last fall while the children's metal cell door. 32 00:02:58,830 --> 00:03:03,040 Let's move to the DC range. 33 00:03:03,770 --> 00:03:06,680 Okay I will wouldn't let my job small. 34 00:03:06,740 --> 00:03:12,250 So I will go to the DC 200 the um uh. 35 00:03:12,260 --> 00:03:16,280 Now I will place the props the chrome on the chrome. 36 00:03:16,880 --> 00:03:21,910 And this one that the arm because I know I will be resigning from the million range. 37 00:03:22,170 --> 00:03:31,890 That said on that display and I will take them adjournment for a very simple uh circuit. 38 00:03:32,060 --> 00:03:36,280 I have it here as you can see we have a lid and that is a store. 39 00:03:36,380 --> 00:03:43,910 As I thought earlier uh in order for this to turn on you must connect it like this. 40 00:03:43,910 --> 00:03:49,610 The uh positive terminal 2 that is a store and the negative terminal the lid to the ground. 41 00:03:49,610 --> 00:03:54,480 And as you can see it's on I need to cut the circuit so I will do the same. 42 00:03:54,650 --> 00:04:01,620 I'll connect uh the negative turn round to this but the most optimal I would permit to throw this uh 43 00:04:01,760 --> 00:04:05,780 device or throw the props of this multimeter. 44 00:04:06,410 --> 00:04:20,300 So let me just talk it up here as you can see now I have this blob on this prop I will connect the negative 45 00:04:21,290 --> 00:04:27,380 to the battery and connect the other probe to the distal multimeter.
