00:00:01,290 --> 00:00:04,840
Now let's talk about bulb or lamp.

2
00:00:04,980 --> 00:00:12,460
The physical appearance of rusted or burnt out bulb is like this if it is attached just tone bulb.

3
00:00:12,690 --> 00:00:21,240
You can see that there is our broken inside it this broken wire means that this lamp is no longer working.

4
00:00:23,090 --> 00:00:30,290
If you have another type of flame and you want to know if it is working or not you can simply hook it

5
00:00:30,290 --> 00:00:34,550
up to the power and see for yourself if it is working or not.

6
00:00:34,550 --> 00:00:35,560
This is at will.

7
00:00:35,870 --> 00:00:36,950
Vol Plum.

8
00:00:37,010 --> 00:00:38,000
As you can see.

9
00:00:38,150 --> 00:00:42,680
So if you have connected twelve volts to its terminal and if it did light.

10
00:00:42,710 --> 00:00:44,240
This means that it's working.

11
00:00:44,250 --> 00:00:46,130
Otherwise it's not.

12
00:00:46,130 --> 00:00:52,730
Or in some cases you can use the continue artist in your digital multimeter.

13
00:00:52,730 --> 00:01:01,010
THE Busted bulb will give you infinite resistance which means that it's open and there is no continuity.

14
00:01:01,490 --> 00:01:05,780
While the good bulb will give you low resistance but not zero.

15
00:01:05,930 --> 00:01:15,250
And in most cases it will give you beep or buzzer when you are trying this with the continual test or

16
00:01:15,260 --> 00:01:17,940
continue to function in your digital multimeter.

17
00:01:18,200 --> 00:01:21,200
Just like the one that we spent in the previous lesson.

18
00:01:21,260 --> 00:01:24,080
Now if it is connected it will give you Abebe.

19
00:01:24,200 --> 00:01:26,930
If not it won't give you anything.

20
00:01:26,940 --> 00:01:36,470
Or if you use the resistance measurement test it will give you a very low resistance if it gave you

21
00:01:36,860 --> 00:01:38,960
a high infinite resistance.

22
00:01:38,960 --> 00:01:41,180
This means that the bulb is blocking.
