Hello and welcome to this annual on inside Chad to you how you can easily test a transistor.
So first let me explain this theory.
Basically a transistor has three terminals or a base collector and a metal
and we have two types of transistors B and B and and beyond.
We all need to concentrate on that out in the middle here down on the B.
Okay let me just focus on this area now.
First thing you need to know before this thing a transistor to know.
After all if it's working or not is to identify the base so the base can easily be identified.
If you use the digital multimeter on the diode reading you know because basically a transistor consists
of two diodes and the two terminals that want to give a reading.
Both ways are the collector undependable.
This means that the first thing that we are able to identify is the base.
So if we found two terminals that give no readings you can easily know that these statements are a collector
altimeter.
The base is that terminal that we used and that these two didn't give reading with.
So we identified the base now after identification of the base you need to know if this is a B and B
or Ambien.
This can be done by simply testing the base using the positive terminal of the digital multimeter and
try to get a measurement out of these two.
If the base gave reading which is connected to positive terminal this means that the transistor is be
unbeaten because it's positive in the metal while if we connected the negative chairman of the digital
multimeter and it give what gave a reading with these two terminal.
This means that this transistor is B and B the last step here is to identify the collector unlimited.
The inventor is the terminal that gives a higher reading than the collector.
When connected to the base.
So if we connected these to the collector at the base of the base and diameter it should give us a higher
reading than when we connect these two term now.
I will do this in practice so you don't have to worry about anything.
If you didn't understand my explanation now it will become clear when we do this in practice.
But the main thing that similarity is first identified the base by finding the two terminals that gives
no readings together both ways.
So you both doubles the terminal of the stomach middle here and then you get up here to give no reading.
If your affairs these two terminals the positive here on the negative here it will give no reading.
So basically I find the base which is the third now.
The next step will be identifying if it's beyond your unbeaten by knowing the base voltage is positive
or negative so step will be identifying the collector on the meter.
The one that will measure all will give a high rating with the base will be the emitter.
The other one is the collector.
The next lesson I will show you this in practice.
So stay tuned.
Thanks for watching this listen.
If you have any questions please ask and if you aren't able publicly.
