00:00Assalam-o-Alaikum
00:03Today we will work on this rectifier.
00:06This is our rectifier.
00:09There is also a bridge in this.
00:11Please pick up the bridge from there.
00:13There is a bridge. This is also a bridge.
00:15I will show you that too.
00:17That is also a bridge.
00:19This is the bridge that we usually use in kits.
00:21This is the bridge in the kit.
00:23You just saw it.
00:25Actually, I am making this video only because
00:27this brother is our student.
00:29He has come to learn work from us.
00:31I will train him along with you.
00:33Where are you from?
00:35I am from Dera Lahar, Balochistan.
00:37I have come to learn work from him.
00:39Name?
00:41Sajid Hussain is my name.
00:43In this,
00:45I will also train him a little.
00:47So that you also have a little awareness
00:49about the work.
00:51What is it? What is the system?
00:53In this,
00:55See this.
00:57Our electricity comes here.
00:59There are two voltages here.
01:01AC voltage and DC.
01:03What is AC?
01:05We call it
01:07One is AC.
01:09One is DC.
01:13AC is alternative current.
01:15DC is dead current.
01:17There are two voltages.
01:19We will not go into much detail.
01:21The video will be long.
01:23Because
01:25Understanding this is also very important.
01:27It is very useful.
01:29Because we do this work for students.
01:31We don't make videos just like that.
01:33In this,
01:35See the frequency.
01:37These are our
01:39Sine wave.
01:41It will be one.
01:43There is a zero line in the center.
01:45And one is our
01:47Square wave.
01:49These are like this.
01:51You must have seen often.
01:53The fans start making noise on UPS.
01:55They don't have the right sine wave.
01:57This is the square wave.
01:59And this is the triangle wave.
02:01This is also there.
02:03This is less and this is more.
02:05These are right.
02:07These are also there.
02:09In these, the frequency is
02:11The frequency we get here.
02:13This is 50.
02:15In this,
02:17AC voltage.
02:19I have kept the transformer here.
02:21Because work can be done easily here.
02:23So that we don't have to worry.
02:25The rest
02:27On 220,
02:29The frequency we have
02:31That
02:33On AC
02:3550
02:37Hertz
02:39And
02:41Here
02:43We have installed a transformer.
02:45For example, 10 volts.
02:47Or
02:49Whatever you take.
02:51In this also
02:53Its frequency
02:55Hertz will be 50.
02:57And this is its
02:59Sine wave should also come.
03:01When
03:03When we put it with a rectifier.
03:05So the arm meter
03:07Our arm is this one.
03:09This will tell us
03:11DC.
03:13But certain DCs say it.
03:15They will come like this.
03:17Okay.
03:19Now I will tell you practically.
03:21What is it?
03:23And how does this bridge work?
03:25Let's work on this first.
03:27We will go after that.
03:29Look at this.
03:31The camera will show you.
03:33Look at this.
03:35This band is this one.
03:37We make this.
03:39I make it a bridge.
03:41From here
03:43Look at this.
03:45We made it.
03:47By putting it here
03:49And look at this.
03:51And look at this.
03:53From here
03:55And it will be here.
03:57Now these four
03:59We have made it a bridge.
04:01We have put four rectifiers.
04:03So what happens
04:05From where we
04:07Look at this.
04:09This is the mark on one side.
04:11This is the mark on the other side.
04:13This is the mark of anode and cathode.
04:15This
04:19Look at this from here.
04:21Here
04:23One line and
04:25We give it from here.
04:27So this
04:29Now in this
04:31AC from here
04:33The second line from here
04:35AC is given.
04:37From here
04:39DC positive
04:41And from here
04:43Neutral negative DC
04:45Look at this DC
04:47And we get this DC.
04:51We get DC.
04:53This is done.
04:55Now the problem comes in this
04:57In the normal routine
04:59From here
05:01You will think
05:03How does this DC happen?
05:05Now how much frequency
05:07How much frequency
05:0950 Hz
05:1350 Hz is its frequency
05:15Now
05:17Neutron proton
05:19There are two such
05:21But I am making a short video
05:23Just to tell you
05:25If you go deeper, it will be very long.
05:27Look at this
05:29Neutron proton comes
05:31When
05:33Neutron comes here
05:35When Neutron comes
05:37It will pass here
05:39We will get Neutron.
05:41We will get negative.
05:43And in this same line
05:45When proton comes from here
05:47It will pass from here
05:49We will get positive.
05:51Now this action happens very quickly from here.
05:53I am telling you
05:55Look at this
05:57Neutron from here
05:59Then proton from here
06:01Now
06:03Here
06:05Frequency
06:07Look carefully
06:09This DC line came here
06:11And this positive line
06:13Now from here
06:15When we check here
06:17So
06:19Voltage will be the same
06:21But here
06:23Frequency
06:25100 will show
06:27Frequency
06:29100 Hz will start here
06:31Here
06:33But here
06:35Voltage will be the same
06:37Whatever your objective is
06:39It will do
06:41Now here
06:43When frequency is 100
06:45Then we will put this filter here
06:47Here
06:49On positive
06:51And on negative
06:53We will put here
06:55We will put here
06:57Here
06:59Sorry
07:01We will put here
07:03When we see pole
07:05Then here
07:07Frequency
07:0900
07:11Frequency
07:13Hz
07:15Now we will do practical
07:17We will do practical
07:19And this is the way to check
07:21This is
07:23I try to make
07:25Video quickly
07:27I try to make video quickly
07:29I try to make video quickly
07:31I try to make video quickly
07:33So that you can see
07:35This is a digital meter
07:37What happens in this
07:39This bridge
07:41This is negative
07:43This is positive
07:45I have put this meter on diode mode
07:47After that
07:49This is
07:51This is AC
07:53This is DC
07:55Sorry
07:57Negative wire meter
07:59When I put here
08:01Negative will pass through
08:03First here
08:05We have to see
08:07On AC
08:09Now this is the second AC
08:11Now this is the third
08:13See here
08:15It will show double
08:17As you see
08:19I put the same
08:21As it is made
08:23Both sides
08:25Both sides are positive
08:27Negative
08:29One side is anode cathode
08:31When I put it
08:33It is positive
08:35See it is right
08:37Now I am checking it
08:39Meter is also with
08:41Both things should be visible
08:43I put this meter on diode mode
08:45As I told you before
08:47I am putting it on positive
08:49I am putting it on positive
08:51This is reading show
08:55Sorry
08:57Meter is not working
09:01See
09:03I have put it here
09:05When I put positive
09:07Sorry negative
09:09This is positive
09:11Negative will pass through
09:13Negative will pass through
09:15This is AC
09:17This is second
09:19See
09:21Double reading
09:23This is correct
09:25Now we will do
09:27Practical
09:29See
09:31How it works
09:33See
09:35Now I am putting
09:37Transformer
09:39Practical
09:41So you can understand
09:45This video is very useful
09:47You can watch it fully
09:49It is not useful
09:51If you do not like
09:55The one who will like
09:57Will understand
09:59What we are making
10:01Other people do not like
10:03They do not know
10:05That this work also has to be done
10:07See
10:09This one
10:11See
10:13I am putting AC voltage
10:15If I check with meter
10:17See
10:19Here
10:21See
10:23I am putting meter on 200
10:25See
10:27I am putting easily
10:29Otherwise it would be short
10:31See
10:33Voltage came here
10:35See
10:37Voltage
10:39See
10:41Voltage
10:43See
10:45See
10:47See
10:51See
10:55So
11:01Great
11:03Great
11:05Great
11:07Great
11:09Great
11:11I will tell you everything in a good way, this is what I try to do while working
11:16Look here, this is AC, sorry I said AC, this is negative and this is on the side
11:21Look here, sorry, this is positive from here, now it will not let negative pass from here
11:27Now as we talked about this, look here, I explained this, it will not pass from one side
11:34Now I have put this in the same way, because it is the third color, I have put it in double color
11:39There is no etiquette of negative and positive in this, because if you put the thing, if there is a fan, it will run straight, it will be on the DC from the other side, there will be no difference on this side
11:49If I now see this, it is a matter of work here, see it very carefully, no doubt, you can watch the video by backing it
11:57Look here, there is a mark here, it has to pass neutron from here, not proton, I am putting it here like this
12:07Now what will happen, if I check it wrong, you know that there is a minus sign on the meter, you know when you check it wrong
12:18So this neutron will give it to me here, and here the proton will come, so that it is positive, now I am putting it here
12:28And do not put it like this, see the meter is not showing wrong, the meter says that the DC mark is also pure, the proton is complete and it is DC
12:36But if I put it like this, then see it is showing negative, this one and that is ours, see, if this is wrong, then it will show wrong, see, see the minus has come
12:49And with this, and after this, I will now change it, see, I have done it like this, now what is this, it will not let the neutron pass from here, it has become negative
13:02See, now I will tell you this thing, see, I am putting it upside down, see, I am putting negative here because it has become positive, now it has become positive
13:11Now it will show negative, see, see, the minus sign has come, at the same time, okay, now when I put it from here, see, it will show the correct proton here at the same time, this has become negative, this is positive and the meter says that it is DC
13:25Now we will check these things on DSO, that what does DSO tell us, we will check it, see, first of all I put it with it, we have to check DSO, see the light, if it is not closed, if it is not fast, then see
13:42Along with this, it is like this, now we will show on it, see, because the meter has told us pure DC, now see, this is positive, this is negative, as I put it here, see, what I have made here, see, show it, show it
14:00This is what you have seen, this has become our DC, show it, okay, this is done, but along with it, we will check it together, now its frequency, which I told you earlier, see, it has 50 Hz here, it has 50 Hz coming, see, okay, it has 50 Hz, see, the frequency is coming
14:25But now we will put it on the bridge, which is 100 Hz, we will show you, see, the bridge will be put, you have to see the bridge, see, here, see, yes, this one, see, the anode cathode is on this side, I will give it AC here, and after that I will give it DC here, sorry AC, the other line
14:49Here I got my DC, now whenever I put it here, then we will see two things of it, see, one is that the setting of DC has changed, okay, it has become like this, on putting the bridge, show it here, yes, it has become like this on putting the bridge, and now I will see its frequency, which we will check, how much it has come, check this Hz, 101 or 100, see, okay, this is its Hz, now the next thing is that
15:19that this filter is in my hand, now whenever I put it, so first we will pass it here, see, from both sides, both things can be seen, how I am touching it, this property is to be seen, positive on positive and negative on negative, whenever I touch it, then you have to see that at the same time, show this frequency, it has become zero, at the same time, okay, see, it has become zero, I remove this, so at the same time, see, it will come on 100 frequency, okay
15:48so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency, okay,
16:18so at the same time, see, it will come on 100 frequency, okay, so at the same time, see,
16:25it will come on 100 frequency, okay, so at the same time, see, it will come on 100 frequency,
16:32okay, so at the same time, see, it will come on 100 frequency, okay, so at the same time,
16:39see, it will come on 100 frequency, okay, so at the same time, see, it will come on 100
