Hello everyone, how are you? Welcome one more time
This is a bonus class
Because this is something that I have to tell
so we can understand a lot of things that we will see
on future lessons or something that you still need to understand from previous lessons
So, let's get started
Hello everyone
Edgar here again, greeting you from "YoReparo"
How are you?
Today I came to the living room
although the light hit me in the face
but this sofa it's more comfy
than the chair that I bought
Today's lesson it's very quick
it's about equivalences, ok?
First, let's go to the tablet
to recall what we're going to measure
which means Volts
Volts
We'll measure Amps, ok?
and we'll measure Ohms, right?
These are the measurements that we're going to do
the measurements that we're going to see henceforth
What are the equivalences?
The equivalences are when I say "Milli", "Micro", "Kilo"
when I say
all of them
so whatever measurement we are using
we're going to have equivalences on it's measure
What does it means?
Let's start with "Volts"
When you check your multimeter
you will see 0.000
everything over here will be "Milli"
and over here will be the "Unit"
So we need to learn the next
this is a Unit
in this case, 1 Volt
right?
Then we have "Milli"
it's everything on 0.001
Then we have "Micro"
the symbol of "Milli" it's "m"
the symbol of "Micro" it's "µ"
and that will be 0.000 001
that would be "Micro"
We can also have "Nano"
symbol "n"
it would be 0.000 000 001
And we can also have "Pico"
it's a very small measurement
it would be 0.000 000 000 001
Now, up here
we will have "Kilo"
which means
symbol "K"
and it would be 1000
which means it will be 1000 times the unit
Then we have "Mega"
which means it will be 1,000,000 times the unit
and it's symbol it's "M"
and it would be 1 000 000
So this information over here it's gonna help us, ok?
Let's say
this can be used on Volts, Amp and Ohms
With this I can start looking for the equivalences
For example
knowing this information that I gave you
I can say, for example...
when I see this
0.550
What would this be?
This would be
millivolts
milliamps
Then, this
represents this
Now
if I have 0.050
this would be 50 millivolts
or 50 milliamps
If I have 0.005
that would be
5 millivolts or 5 milliamps, ok?
Why I'm explaining all of this?
Because we're going to start view power supply
we'll see consumptions
and we'll see all of that
and it's very important that you know this
so
I can see
a resistance of 1000
right?
of 1 K
that means this resistance is 1 Kilohm
the same way we can say the resistance is 100 Ohms
Now, I need you to understand very well about the multiples
check, recap, this info that I gave you
because this it's gonna help you to understand what are the equivalences
we have the Unit
and we start from the Unit
and we can go down or up
Okay
That's all from the lesson today
a very short lesson
but I always hope that you can take advantage of it and make the best of it
Hugs to everyone, take care
and I'm going to move the camera over there because the light hits me in the face
Hugs, bye!
