Now let's talk about bulb or lamp.
The physical appearance of rusted or burnt out bulb is like this if it is attached just tone bulb.
You can see that there is our broken inside it this broken wire means that this lamp is no longer working.
If you have another type of flame and you want to know if it is working or not you can simply hook it
up to the power and see for yourself if it is working or not.
This is at will.
Vol Plum.
As you can see.
So if you have connected twelve volts to its terminal and if it did light.
This means that it's working.
Otherwise it's not.
Or in some cases you can use the continue artist in your digital multimeter.
THE Busted bulb will give you infinite resistance which means that it's open and there is no continuity.
While the good bulb will give you low resistance but not zero.
And in most cases it will give you beep or buzzer when you are trying this with the continual test or
continue to function in your digital multimeter.
Just like the one that we spent in the previous lesson.
Now if it is connected it will give you Abebe.
If not it won't give you anything.
Or if you use the resistance measurement test it will give you a very low resistance if it gave you
a high infinite resistance.
This means that the bulb is blocking.
