- 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.
