No. A unijunction transistor (UJT) is entirely different in design and application than a bipolar junction transistor (BJT). The UJT works on the principle of voltage modulation of the effective substrate resistance, while the BJT works on the principle of current amplification from one junction to the other, usually base-emitter to collector-emitter.

How do you make ujt with npn and pnp transistors?
You dont. A UJT is a much simple device than either of those BJT's Maybe you want to make a multivibrator out of BJT's?
Ujt relaxation oscillator?
It is sawtooth waweform genrator
What does intrinsic stand off ratio of an ujt determine?
The amount of potential to forward bias it
Why bjt is not used of fet in building logic circuit?

How do you replace the skin of a drum?
You can not, you need to replace the skin with a new one.

Difference between bjt and ujt?
UJT is the voltage controlled device.in which only one mejority carriers are responsible for current flowing. UJT is one junction transistor and it is three terminal emitter and two base. BJT is the current controlled device. in which both mejority and minority carrier are responsiblefor current flowing. this type of transistor consists of two junction and three terminal these are : emitter , base , collector.
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 types of transistors are the following - BJT PCT UJT SBT FET GJT AJT DFT?
The BJT is the bipolar junction transistor, the PCT is the point contact transistor, the UJT is the uni-junction transistor, the SBT is the surface barrier transistor, the FET is the field effect transistor, the GJT is the grown-junction transistor, the AJT is the alloy-junction transistor, and the DFT is the drift field-junction transistor.
Why ujt used as an oscillator?
why ujt used as amplifier
Operation of UJT and block diagram?
Explaine operation of UJT .
Is ujt is a uni polar transistor?
UJT is known as Uni Junction Transistor
How to genrate sawtooth wave by using ujt?
by connecting the ujt with proper biasing resistors
In ujt what does the j stand for?
For many people the letters UJT stand for Unitary Junction Transistor.
Why bjt is bipolar?
Bjt is bipolar because in bjt the conduction of current is due to the electrons as well as holes
Why ujt called current controlled negative resistance device?
The On/OFF action in UJT is controlled by emitter current
Is a UJT a voltage controlled or current controlled device?
voltageCurrent between the two bases of the UJT sets up a voltage gradient in the semiconductor. When the voltage on the emitter of the UJT rises high enough to forward bias the emitter-base junction at the voltage of the interbase gradient where the emitter is located, the UJT "turns on".
