Hello and welcome to this annual us on which I'll explain to you how to dust out an inductor uh basically
inductor is a coil.
And here we have a Transformer.
It has a Primary coil.
The second recall so we can use these two coils to demonstrate inductor government thing.
So it's really easy to use us need to bring your digital multimeter and apply these tools to the com
and the Volts on the road and her seeding as you can see here the read on the com the red and the Volt
on the old Hertz and the Black is on the cone.
NOW MOVE THIS DIAL to the diode or the um let's say sound Bazar or connectivity uh pattern and make
sure that it's working by simply destroying this as you can see it's working.
Now if you test the binary code it has a very high resistance so it won't display or it won't show connectivity
it will just display that resistance value as you can see we have like a hundred a hundred on resistor
or resistance.
Okay.
One all.
Now the primary distance as you will is it is usually high.
So as you can see here we have one hundred home one hundred on resistor
while the second the resistance is very small very small.
So it's this is because it's taking like 220 volt AC and the biomedical coil and it gives only 6 0 6
volt on the second record.
So this is a center that we have the black wire and we have to blues When we connect these two we will
find half the resistance of the second recall and you can see that using the connectivity test you can
test this out okay media as you can see.
This means that the second the call is working.
Now is this the other one.
Again it's this sound.
This means that this is all connected.
Now most likely when you're just an inductor if it didn't show connectivity or resistance a small resistance
this means that there is a cut in it or there's a problem with that inductor and you have to replace
it.
So there is two types of this for the inductor.
The first one is the connectivity test.
The second one is that a distance test.
So let's test using that as a stance we can match up the resistance.
So this is a sense of type.
So the same resistance must appear on the black and blue on the black on this one.
So the first blue whale will give us that resistance with the black wire which is the very same distance
as between this black white and blue wire here.
So let's test the first resistance OK.
As you can see we have light.
Point eight or point five on the distance on the LCD.
Now we must get our other point five between these two.
Let me just say again point five point four.
So the total distance between the two blue whales will be the sum of these two the distance which is
basically one arm or buoyant clearly
they just fixed this to the table.
OK.
As you can see point eight point seven
and this is the sum of the total distance that we just measure.
This is for the second recall.
It's a very long distance around one arm while the primal core has a very high resistance.
So we put these two this one if you check the LCD you can see that we'll have around 100 ohm OK.
Seventy seven ohm which is like seventy seven times larger than the secondary coil resistance.
So this is how to test the conductance of a coil.
And if it's connected or not if it has a problem or not by testing using the connectivity test here
or using the form test here goes a core it is basically a way of inductor is basically a wire that has
a resistance that you can measure for sure there is other specialized devices for measuring conductance
and it gives you the conductance value not an arm or connectivity gives you the very same conductance
value but we are using this symbol digital multimeter to start out this thing cause buying conductance
digital multimeter would cost you a lot.
So using this symbol device very cheap device you can test conductance using interconnectivity or the
resistance this these other to test you can use to measure conductors if you have any question regarding
this.
You can ask in the currently aboard I'm here to help you.
Thanks for watching.
