- emitter, emits minority carriers into the thin base material
- base, controls minority carrier current flow between the emitter and collector
- collector, collects minority carriers that have passed through the thin base material
While the emitter and collector are named for their electronic functions, the base is instead named for its structural function in the first point contact transistor: it was the bottom part of the transistor that structurally supported the other parts (thus the base). However junction transistors are usually not constructed that way, in most modern junction transistors the collector is the bottom part.

What arer the 3 legs of a transistor?
Emitter, Collector and Base cutoff region, saturation region, and liner region
What happens when the base current of a transistor is decrease?
in a properly biased transistor, collector and emitter current also decrease
How do you find base emitter collector of npn transisitor using notch?
Find the notch in the transistor, turn it towards you, point the leads down. From left to right is the Emitter, Base , Collector.
The device which acts like an NPN and a PNP transistor connected base to base and emitter to collector is?
Triac
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 parts of a transistor?
The emitter, the base, and the collector are parts of a transistor.
What are the parameters 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
What are the three terminals of a transistor?
Emitter, Base, Collector.
Is a diode like a transistor?
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.

What is transistor action?
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.
What are the bias condition of the base emitter and base collector junction for a transistor to operate as a switch?
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.

What do you called the center element between the emitter and collector in a transistor?
The base.
What is darlington configuaration?
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.
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 the base of transistor made very thin?
Base of transistor is made thin just to get Collector current equal to Emitter current.
