It is possible with an ohmmeter usually the can has a tab signify emitter. some plastics devices have the emitter on the right lead looking at the flat part. using an ohmmeter you may check for the two diodes inside.
First hold the transitor facing its flat surface towards you.Then among 3 terminals the right terminal is Emitter,middle one is base & the left one is collecter.
First select the continuity scale of MM (multimeter), then 1st connect the +ve prob to the very 1st leg of transistor, and then connect the -ve prob to the other legs of transistor one by one. repeat same procedure with each leg. If MM shows some value, the higher value is emitter n lower value is collector and remaining leg is obiously base. when MM shows some value we consider the +ve probs leg as desire terminal either emitter or collector.
A: A transistor is actually two diodes back to back. If you know the ohm meter leads polarity then then the diodes can be verified as diodes and the diode polarity therefore ascertain an NPN PNP transistor. Be aware that the ohm meter can destroy the junction for some transistors
The base, emitter and collector can be identified with the data sheet of the transistor, every type of transistor can be different, you can find data sheets easily when you Google the type of transistor.
Emitter, Collector and Base cutoff region, saturation region, and liner region
in a properly biased transistor, collector and emitter current also decrease
Find the notch in the transistor, turn it towards you, point the leads down. From left to right is the Emitter, Base , Collector.
Triac
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.
The emitter, the base, and the collector are parts of a transistor.
# parameter are usually the base current ib,collector current ic,emitter current ie,collector emitter voltagevce,base emitter voltagevbe,collector base voltagevcb which decide the operation &output of the transistor
Emitter, Base, Collector.
No. A diode is not like a transistor, and a transistor is not like (two) diode(s). Taken in isolation, the emitter-base and collector-base junctions of a transistor appear to be diodes, but they are coupled together so that the base-emitter current affects the collector-emitter current.
Emitter, Collector and Base cutoff region, saturation region, and liner region
The transistor has three regions, emitter,base and collector. The base is much thinner than the emitter while the collector is wider than both. However for the sake of convenience the emitter and collector are usually shown to be of equal size. The transistor has two pn junctions that means it is like two diodes. The junction between emitter and base may be called emitter-base diode or simply the emitter diode.The junction between base and collector may be called collector-base diode or simply collector diode. The emitter diode is always forward biased and the collector diode is always reverse biased.
In order for a transistor to operate as a switch, the base-emitter current must be greater than the collector-emitter current divided by a factor of hFe. In this state, the transistor operates in saturated mode, fully turning on.

The base.
A Darlington pair uses two transistors connected to behave as a single transistor with a very high current gain (beta). Transistor-1 has its collector connected to the collector of transistor-2. Transistor-1 has its emitter connected to the base of transistor-2. The base of transistor-1 with the emitter and collector of transistor-2 is used as a single 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.
Base of transistor is made thin just to get Collector current equal to Emitter current.
