UJT(UNIJUNCTION TRANSISTOR) is a three-lead electronic-semiconductor device with only one junction that exclusively as an eletrically controlled swtich andit is not used as a linear amplifier.
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".
A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.
The bulk resistance between the two bases, which will be different for different types of UJT. Consult the datasheet for the value.

Explaine operation of UJT .
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 Timers using UJTs have largely be superseded by timers based on a 555 integrated circuit.
The simplest application of a UJT is as a relaxation oscillator, which is defined as one in which a capacitor is charged gradually and then discharged rapidly.
UJT is known as Uni Junction Transistor
by connecting the ujt with proper biasing resistors
It can be used as a Sawtooth wave generator
For many people the letters UJT stand for Unitary Junction Transistor.
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
