What is the difference between the UJT and BJT transistors?
UJT (UniJunction Transistor): It is a transistor with only one junction and three terminals: an emitter (E) and two bases (B1 and B2). BJT (Bipolar Junction Transistor): This type of transistor consists of two junctions and three terminals, namely Emitter "E", Base "B" and Collector"C". There are two types of BJT, i) PNP and ii) NPN.
What are the example current controlled device?
Bipolar junction transistor(BJT)
Switching speed is high for mosfet or bjt?
generally bjt is faster than fets...because of many intrinsic junction capacitances between ...source and drain and bulk and gate,,,.. but now a days due to advancement in scaling fet is reduced in size sooo much that it became faster than bjt... mosfet is faster because of scaling. small channel length. even though it is slower but distance to be travelled is less
How many terminals does a potentiometer normally have?

What are the three element of a transistor?
For a BJT transistor the three basic elements are collector, base and emitter. For a FET transistor are drain, gate and source which are analogous for the BJT parts mentioned before.

How do you identify the terminals of a 2N2222 BJT from datasheet?
See for example http://www.datasheets360.com/pdf/7308997814572458562 In general, terminals are identified by number and name, with reference to the physical appearance of the transistor package.
How do you identify terminals of BJT?
The terminals of a BJT (bipolar junction transistor) are the emitter, base, and collector. One common method to identify these terminals is to look at the physical package of the transistor. The emitter is usually connected to the most heavily doped region and is often indicated on the package. The base is usually the middle terminal, and the collector is often connected to the remaining terminal.
Why fet is preferred over the bjt?
Disadvantage:Easy to damage when compared to BJT

How many terminals does Heathrow currently have?
Heathrow has two terminals
How many terminals at Bangkok international airport?
Only 2 terminals
The control current of a transistor flows between which two terminals?
The control current of a transistor flows between the base and the emitter terminals in a bipolar junction transistor (BJT). In a field-effect transistor (FET), the control current is related to the voltage applied between the gate and the source terminals, influencing the current flow between the drain and the source. In both cases, the control current or voltage regulates the larger current flowing through the device.
How many terminals are in the Alaska Marine Highway System?
The AMHS has 32 terminals.

What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
What is the difference between jfet and bjt?
FET's (field effect transistors) are unipolar devices because unlike BJT's that use both electron and hole current, they operate only with one type of charge carrier. BJT is a current-controlled device; that is the base current controls the amount of collector current. FET is a voltage-controlled device, where voltave between two of the terminals (gate and source) controls the current through the device. BJT's have a low input impedance ( ~1k -3k ohms), while FET's have a very high input impedance (~10^11 ohms). Consequently FET's have a lower power consumption. BJT's produce more noise than FET's . FET's have a slower switching speed . BJT's are subject to thermal runway while FET's are immune to this problem. BJT's have a higher cutoff frequencey and a higher maximum current then FET's. FET's are easy to fabricate in large scale and have higher element density the BJT's.
