Best Answer

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.

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 Timers using UJTs have largely be superseded by timers based on a 555 integrated circuit.

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".
