I know only two types of transistors, one is with a metal head, another one with a plastic covering.
For the metal one, you could see a little protruding metal piece, the pin near it is EMITTER, the one which is away from that is COLLECTOR and the other is BASE
For the plastic one, one face of it will be flat, make it lie down such that the flat side is touching the ground, now the middle one is BASE, right one is COLLECTOR, left one is EMITTER
For all others where both the sides are flat, check for a dot or circle on it, place the transistor so that you the dot or circle faces you, now the middle one is BASE, right one is COLLECTOR and the other is EMITTER
What else can I help you with?
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.
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
What will happen when terminals base and emitter gets interchanged in a transistor?
It won't work.
Why transistor have 4 wire?
The transistor is a three layer (or two junction) device, emitter, base, and collector (or other designations for variations such as FET's). Each layer is connected to a terminal. Three layers - three terminals.
What are the three terminals of a transistor?
Emitter, Base, 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 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 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
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 are the three terminals of transitor?
base, emitter, collector

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.
