Hello and welcome.
Today we'll talk about that is a store in more details.
We will take a good look at this store.
Defying all resistance defying resistance values OMB's colored code interpretation power dissipation
and we will look at resistors and circuits serious battle and mix.
This is there is a store symbol as we mentioned earlier.
Now let's look at um the first thing with which is resistance defined resistance is the embodiment to
the free flow of electrons through our conductor friction to moving electrons where there is friction
there is he generated all materials except some resistance.
Even the best of conductors unit measure in arms.
So we measure resistance in arms from one divide by tens of arms to millions of on.
Now let's look at resistor types.
There's the VIX value the Variable value the combos aren't resistive material.
The Wild One and Two barometers associated with the resistors which is the resistance value and arms
both are handling capabilities in Watts.
So these are the two most important factors that you must take care of.
When I'm mentioning at a store or dealing with a resistor.
Now if we looked here all hundred armed to the store this is a hundred on that one that one that one.
They came in different sizes as you can see.
So they can handle the different amount of power.
As you can see the the diameter of each one is different than the other.
But the order was all the same value which is a hundred thousand on.
Now let's look at this and know the different sizes between composite and wire one resistor as you can
see here composite types all of these stores could have the same resistance value even for their relative
sizes vary widely.
So as we mentioned in the previous example these all have the same resistance which is a thousand all
but they come in different sizes.
The same here now flocked here.
This is a fixed resistor as you can see this is how it looks.
And this is another shape while in valuable resource total potential means that as you can see here
that we will use and most of the audio devices.
This is how it looks.
This is its symbol and this is how it looks at real life.
Now what really Inside Out is a store as you can see here.
This is at a store Auburn.
There is a stomach tube a metal in the cab as you can see here and a coating to connecting wires and
the two terminals.
And here we can see the printed values and there is also color bands that represent the value of the
resistance.
If you don't have a bolt on me today you can know its value from the color bands.
Now let's look at Reading resistor color codes.
First you need to understand that each of these color has a meaning.
The first one is the first band.
This is the second band and this is the multiplier.
And this is the tolerance.
Now we need to model how to read that as this tool cannot code with any practice in a practice using
one Columbus's term brown black red.
And tolerance band let's look at that one come on resistor terms as a store.
So gold or silver band is art right.
So you need to lift that ban which will be either gold or silver and your right side right hand side
not the color of the two left hand color bands which are here.
The green line the blue one.
The leftmost band is the left hand value digit.
The next band to the right is the second value digit not the color of the third band from the left which
is yellow here as you can see you must know its color.
This is the multiplier multiple the two value digits by the multiplier.
So we will get two digits from here.
Then we will use this multiplier to multiple them.
Um let's look at let's say a more solid example.
But first let us uh look at this uh color codes.
If it's black and existed in the first digit then its value will be zero.
And so on for other cars until you reached the White one which is nine.
If it's the second digit it will have the same value.
While if any of these colors existed in the first band from the left it will be that multiplayer.
As you can see one in hundred thousand.
And depending on whether the right hand band is gold or silver you can add other lines of 5 percent
or 10 percent or in case of no local band.
It would be 20 percent this is a very symbol.
So now let's look if we have one kilometer this tall brown black red and tolerance band let's orient.
There is a story with the tolerance band to the right the gold or silver band.
There is no band we mentioned.
That would be 200 to 20 percent tolerance to this tour let's orient that resistance so the band are
to all the left.
Take note that the two significant digits of that is a total value are going to resented by the two
left most color band.
Note that the left most band is Brown which translates to a value of one.
As you can see here.
Brown means one and um well you must know that moving left to right.
Note that the next band is black.
Black means uh zero as we say as we can.
Let's say this is the black one.
It's the yellow.
This is the second digit.
So now continue moving left to right.
Note that the multiplier band is red which translates to the multiple or multiply out of a hundred.
So multiple that N times hundred it will equal 1000 or one kilo on.
This is a really simple method to measure all different values of the stone with a fat as a store without
using a digital multimeter.
Now reading resistor color codes practical problem if we have an orange orange red yellow Violet orange
brown black brown black brown black lean red red red blue gray or orange orange white orange I need
you to get the value of all of these.
Take a five to translate these values using this table I will applaud the course material so that you
can use them you can use these slides to gain more knowledge the results will be three point three kilo
arm 47 kilo on one hundred on one mega arm two point two kilo six sixty eight kilo thirty nine kilo.
These boards that we use and solve this problem before going any further.
And the next lesson we will discuss board the situation and out of the store.
Thanks for watching.
