Answer: First you have to find the Base, with your millimeter set to diodes play around with the probes between the three pins until you get a reading between one pin to both the other two pins that pin will be your Base, if your red probe is on that pin then it is a NPN transistor, if it is the black probe then it is a PNP, there will be a slight difference in the reading, the pin with the smallest reading will be the Collector and the larger is the Emitter
What else can I help you with?
Why is collector current slightly less than emitter?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
Why is collector current increased slowly with the increase of collector to emitter voltage of a common emitter?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
How does a transistor electronically switch the output on?
A transistor can electronically switch the output by controlling the flow of current between its two terminals, called the collector and emitter. It has a third terminal, called the base, which acts as a control input. When a small current is applied to the base terminal, it influences the flow of current between the collector and emitter terminals, effectively turning the transistor "on" or "off" and allowing it to change the output state.
What arer the 3 legs of a transistor?
Emitter, Collector and Base cutoff region, saturation region, and liner region
Can you use transistor as diode?
its the simplest thing to do. There are three legs in a transistor, one each of collector, base and emitter. So if you need to use it as a diode, just connect either collector-base or emitter-base. Say, if you use an NPN transistor, then the base region will be the anode of diode and emitter or collector will be the cathode of the diode.
What are the 3 legs of a phototransistor?
Emitter, base & collector.
What are the three terminals of transitor?
base, emitter, collector
What are the three terminals of a transistor?
Emitter, Base, Collector.
Why a transister has three terminals?
Because there are three components within a transistor... An emitter, a base and a collector. Think of it like shining a torch at a mirror. The the torch is the emitter, the mirror is the base and the reflected beam is the collector.
What is the usage of third terminal in transistor?
There are three terminals on a transistor. Some have four, where the fourth is a screen.The normal three are Emitter, base and collector. The Emitter emits electrons, the collector collects them and the base controls the flow.
Why is collector current slightly less than emitter?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
Why is collector current less than emitter current?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
How do you identify terminals of BJT?
The terminals of a BJT (bipolar junction transistor) are the emitter, base, and collector. One common method to identify these terminals is to look at the physical package of the transistor. The emitter is usually connected to the most heavily doped region and is often indicated on the package. The base is usually the middle terminal, and the collector is often connected to the remaining terminal.
What is the emitter base collector in 2N5777 photo transistors?
1st pin is emitter then collector and base
Why is collector slightly less than emitter?
some of emitter current goes out base instead of collector
Why output of common emitter amplifier is inverted?
In a common emitter amplifier, the base-emitter current causes a corresponding collector-emitter current, in the ratio of hFe (beta gain) or collector resistance over emitter resistance, which ever is less. Since this ratio is usually greater than one, the differential collector current is greater than the differential base current. This results in amplification of the base signal. As you increase the base-emitter current, the collector-emitter current also increases. This results in the collector being pulled towards the emitter, with the result that the differential collector voltage decreases. This results in inversion of the base signal.
Why is collector current increased slowly with the increase of collector to emitter voltage of a common emitter?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
