Why ujt used as an oscillator?
why ujt used as amplifier
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".
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.
Why UJT triggering circuit is superior?
DPE?
What is a UJT?
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.

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 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 Timers using UJTs have largely be superseded by timers based on a 555 integrated circuit.
