The operation of the circuit is as follows: C1 charges through R1 until the voltage across it reaches the peak point. The emitter current then rises rapidly, discharging C1 through the base 1 region and R3. The sudden rise of current through R3 produces the voltage pulse. When the current falls to IV the UJT switches off and the cycle is repeated.

What are the applications of ujt?
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.
Does anyone have a schematic for d-cell relaxation oscillator?
Relaxation oscillators just requie a certain voltage range in which to operate, so most any schematic for one will work, providing you have enough D cells to be able to supply the proper voltage.
Operation of UJT and block diagram?

How to genrate sawtooth wave by using ujt?
by connecting the ujt with proper biasing resistors
Why ujt is not used as amplifier?
The UJT (Uni-Junction Transistor) is not typically used as an amplifier because it does not have the necessary characteristics for linear amplification. Its operation is primarily based on negative resistance and it is designed for triggering applications, such as in relaxation oscillators and timing circuits. The UJT has a limited control over output current, making it unsuitable for applications that require linear gain. Instead, BJTs and FETs are preferred for amplification due to their ability to provide a stable and linear relationship between input and output signals.

What is the procedure for testing the circuit of UJT relaxation oscillator?
Depends on what you need to know about it. First off, I'd use an oscilloscope. If it's set up correctly and you know how to `count graticules' that's really all you'll need to learn almost everything about your oscillator. IT should show you the wave forms at certain connection points, voltages as well as giving you some indication of the frequency. And if you want to know the current draw, you should probably have some type of milliamp meter on hand, which can usually be found in most miltimeters.

Is ujt is a uni polar transistor?
UJT is known as Uni Junction Transistor
How does a signal generator work?
For ac usually is a non linear resistance that can be used to change frequency Or a relaxation oscillator can supply square waves and filter it to get the basic frequency.. piratically all of them needs some kind of positive feedback
