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.

Why ujt used as an oscillator?

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?

Characteristiccs of UJT?

The characteristics of a UJT are: stable triggering voltage, negative resistance, high pulse current capability and low value of triggering current.
