In the previous video we saw how to measure in volts, today we are going to see another function of our multimeter that is continuity, so join us
young how are you? Edgar here greeting you again from Yo Reparo, I hope everyone is well here it is already getting dark but we continue recording we continue creating content for all of you, I hope you liked yesterday's class
And another very important thing is I hope you have put it into practice, because it is useless for me to be here recording that I am explaining to you if you do not put it into practice
so it is very important that what they are doing is they see me, they grab a plate and they start practicing.
Now for all those who already know what is being explained, I have several videos on the channel about many failures
right now I am in Guatemala pitifully, cell phones are coming to me to repair but they have been very easy cases that I have not wanted to record because they have been things like an antenna playing a capacitor or a circuit all stopped and that is why it did not turn on or things like that
So I did not want to upload what they are sending me, but as soon as I have a repair as we had before, I will record it and upload it to the channel
my idea is that we learn everything, that we continue to grow but above all that we take advantage of this time that we are at home
the truth is that these times are very difficult, I know that many are discouraged, many are losing the desire to continue, the faith to continue but hechemole you win, this changed the plans of many people for this true virus...
but I tell you that we are going to get out of these and you have to think how you are going to get out, you rested and you are going to get out aah, rest 2 months and have a good life or study, get ready and today I am one step ahead of what I was me previously
don't compete with anyone, compete with yourselves try every day to strive to learn something to take advantage of every minute every hour of the day,
so that when all this is over you said well it is true not to generate, not to work maybe 2 months but I learned
and now I'm super detached from what was previously
but well, this is not a motivational video although what I want is to send many blessings to all
and then collaborate a little as I tell you, here I stayed in Guatemala because of the virus, I did not continue traveling anymore
for the moment we are rescheduling the courses if they are going to be given or if they are not
but always taking advantage of the time to be able to help them and to be able to offer them something
because I tell you this, because maybe they look at me and say Edgar no longer wants to repair, he no longer wants to do anything
It is not that, I simply do not have to repair, I do not have to study, I do not have plates of iphone x, iphone 7, iphone 8 a lot for me to start studying
So I try to have what little I have of what always falls to be refreshing all the content
well I'm not going to continue with this, in today's class we are going to be learning what continuity is
which is continuity, where we are going to be occupying it, so that I am going to occupy it, all that it beeps is land, which is that of continuity
let's remember that what we are doing continuously is measuring a resistance, we are also measuring a resistance
resistance we measure it in ohms but because I will not measure, but because I will not measure if it gives resistance because I do not measure it in ohms and what is the difference
in continuity what happens is that it is a sound resistance, what does that mean?
the resistance depending on the multimeter goes from 1 ohm to 70, 75 ohms and all the lines that are below that range
then they will beep, that's when I tell them it's a sound measurement call it that
we are measuring a resistance that when we are below 70 beeps, I measure 10 ohms it will beep I measure 50 it will beep
but for example I measure one that measures 1000 or one that measures 200 so it no longer beeps
so that is the difference that we are going to be occupying continuity or resistance that we are going to see in this case ohms that we are going to see later
then we will go here to the plate, to measure measure resistance we will not have the phone connected to the source
we are not going to have it on, we are not going to have anything, we are going to put our multimeter here
remember in the multifunction function and we will put here with the function button
I am going to pass here so that you can see better we are going to put it here, we have to put it into function here and we are going to put it in the continuity symbol
what is this as a speaker
before continuing I need you to do the following test, you will grab your meter the continuity and you will touch its tips
It will beep, and what I need is for you to see its multimeter, to see that my land, or my continuity, or my resistance that is touching this is 0.0
I mean that it means that my resistance or my continuity is zero
because I tell you this, because many of you are going to suddenly play and 0.09, 0.05, 0.04, 0.03, 0.01 will appear
What does this mean? This is very important for you to know because the resistance you get from touching the tips is the lowest resistance that your multimeter is reading.
that means that you are going to touch a positive line and you are going to beep
but it will beep because it is in the range of 1 to 70, for example, then it will beep, but not only because it beeps, it means it is land
if you already know an example, this is an example, these are concepts for us to understand
If you already know that your resistance when touching the tips is 0.09 or 0.009, an example
and they touch a positive line and 0.50, 0.20 appears and it is beeping at them, that line is of low resistance
and that's why your multimeter is beeping at you, I have 2 plates here, hopefully we will find one that can beep at the 2 ends to explain what I'm saying
so what is resistance? remember that for more, any component will always have a small resistance
a resistibility to the passage of electrons, any component for my good that is I could tell you
then there will always be a resistance, he will oppose ok and we will try to read that
right now in continuity is much easier, why? Now we are going to go now if the microscope, we have here our multimeter
we have it on a resistance scale and it's in OL right, so let's start
to check resistance no matter the polarity of the tips, then what do we do? we are going to put an earth point and with the other we are going to check
for example I touch the negative line
and my multimeter sounds
it sounds because let's agree that the passage of electrons is free I am playing negative so the electrons are meeting
there is no resistance there, that is, nobody opposes the electrons, so there is free flow of electrons, so this will beep because there is no resistance
because the resistance is low in this case it is earth, then it will beep. but for example if I touch the negative, look don't beep ok
right now we are seeing continuity, everything has to beep we are not seeing ohms or resistance as if ok
in theory we are measuring resistance but in continuity
then I touch and it doesn't whistle this means that there is a resistance greater than 70 ohms between the electrons and this line, between earth and this line
we are going to play another line, and I play no whistle, I play and whistle because this is land and this is the positive one
let's see if we look for another plate here
we are going to remove
this part of here
let's play
is
ok if you noticed there weenie but
quickie it
quickie took off
We are going to look for a plate of the few that I have here for tests
that unfortunately I have not managed to get many plates here
here in Guatemala, we are going to measure another
we are going to measure another line here, this line here. Why am I measuring close to this? because these lines are of low value
ok for example this one, look at this
this is beeping, this is a clear example look, but look at the multimeter gives me 10.3
it means that that line if ohmneaje is so low that the multimeter finds it in continuity
because in continuity I am measuring a resistance that goes from one to 70, any line that I find in that range will beep, so look at the difference
if i play here
if I play here it gives me 8.06 but if I play here
it gives me 0, what happens when I touch the 2 tips, what is the resistance of my tips?
0, so that's ground, that's short. Now if I touch this
and it gives me 8 that is not land, that is a line with low resistance, a line of low resistance we call it
so what he wants you to understand is that not everything that whistles is earth or is short
I hope you understand me the same this we will continue to see in many classes later
so to end this class let's agree, continuity we are measuring the resistance of a line that being low value, from 70 down
It will beep, it is a sound measurement. we are measuring the resistance but when it has a low value it beeps ok
so we are going to stay here in today's class and do not miss tomorrow's class because it will also be very good
always remember to practice listen, because the idea is that I teach you a little bit and you practice
a pleasure to always greet you guys, take good care of yourself and see you in a next video
bye!
