Operation of UJT and block diagram?
Explaine operation of UJT .
How to genrate sawtooth wave by using ujt?
by connecting the ujt with proper biasing resistors
Why ujt called current controlled negative resistance device?
The On/OFF action in UJT is controlled by emitter current
What is an UJT timer?
UJT is an abbreviation for (Unijunction Transistor) the electronic component that is at the heart of a simple timing circuit. A UJT timer is a circuit used in an electonic system to deliver a specific time. For instance, a 30 second UJT timer might be used to turn on a Green traffic signal for 30 seconds, then turn off. UJT is a specifically cheap way of doing this type of timed signal. Timers using UJTs have largely be superseded by timers based on a 555 integrated circuit.

How do you identify the terminals of unijunction transistor?
Usually UJT's come in a metal can package. 1) Hold the UJT downwards (seing its terminals). The one in the middle, near the tab, is the emmiter terminal. With this one "north-wise", the left terminal is B2 (west) and the right terminal (east) is B1.
In ujt what does the j stand for?
For many people the letters UJT stand for Unitary Junction Transistor.
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.
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
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".
Can ujt be used to trigger scr?
no
What is the basic applicatjon of a ujt?
oscillator
What is inter base resistance in UJT?
The bulk resistance between the two bases, which will be different for different types of UJT. Consult the datasheet for the value.
