Can transistors have four legs?
In case of a bipolar junction transistor, we have only three terminals (legs). They are emitter, base and collector. But, in case of a MOSFET (metal oxide semiconductor field effect transistor), we can have four legs. They are source, drain, gate and substrate. The substrate is not being shown in some notations of MOSFET. But it does exist. Hence, a MOSFET has four legs.

How do you find transistors?
A transistor have 3 legs. B, C and E. You can measure the resistance between the legs with a multimeter in order to get a good indication of its condition. If the resistance between any of the 3 legs are close to 0 Ohm (often 0.1 to 6 Ohm) then the transistor is most likely burned and no good any more. If the resistance is above 200 Ohm, then the transistor is most likely burned as well. Note: A good transistor will measure different values depending on where you put probes. If the probes indicate an awful lot of resistance then try to switch the probes and measure again. If resistance is the same, then it is burned. If not, then it is likely OK. It is often difficult to tell if your transistor is actually a Fet or a Darlington. try to search internet for proper data on your 'transistor'. Small signal transistors are often burned open between legs (very large resistance) where as large transistors often shortcut between legs (Very low resistance between legs). I find the C and E leg to be easiest to diagnose a transistor on. If the resistance both ways are the same, then it is no good. Note: In order to 100% determine a transistors condition, then you often would need to desolder it first. All the other components on a printboard will make it harder to diagnose (unless it has shortcut). ANSWER: pay attention to the probes polarity and whether is an PNP or NPN . For an NPN The positive lead goes to the base and either other lead will show resistance reverse the leads and repeat now both reading should be hi resistance. For the PNP SAME PROCEDURE EXCEPT THE POLARITY OF THE LEADS ARE REVERSED
What is Si transistor?
A silicon transistor is a transistor made of silicon.
What are the Similar transistor for 221334 PNP transistor?
Similar to a 2N3906 PNP transistor
What is the function of the legs on a transistor?
as the name suggest transistor means to transfer resistor, it is an electronic device,
Why transistor is called so?
transistor. This word is a blended form of transfer of resistor. The legs of transistor (collector, emitter,base) transfer the resistance. So it is called as transistor

How do you judge the 3 legs of a transistor?
There are standard pin layouts for the various package types, but if in doubt, check the datasheet for the device in question.

Why do transistors have 3 legs and what are they called?
the three legs in a transistor are known as E B and C. They stand for Emitter, Base and collector. Two of them are input and one is an output. so you have two going into the component and one that goes out. hope this helps i am also doing an assignment on this and found this out.
