The structure of a UJT is quite similar to that of an N-channel JFET. The main difference is that P-type (gate) material surrounds the N-type (channel) material in case of JFET and the gate surface of the JFET is much larger than emitter junction of UJT.
FET (Field-Effect Transistor) and UJT (Unijunction Transistor) are both types of transistors but operate differently. FET is a voltage-controlled device, while UJT is a current-controlled device. FETs are commonly used in amplifiers, while UJTs are often utilized in oscillators and timing circuits.

What is the difference between jfet and bjt?
JFET (Junction Field-Effect Transistor) is a voltage-controlled device where current flow is controlled by an electric field across a semiconductor junction. BJT (Bipolar Junction Transistor) is a current-controlled device where current flow is controlled by the amount of current entering the base terminal. JFETs are majority carrier devices, while BJTs are minority carrier devices.
What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is the difference between 164 and 220?
The difference between 164 and 220 is 56.
Define the 'potential difference between the ends of a conductor'?
Potential difference between the ends of a conductor refers to the electrical energy difference per unit charge between two points in the conductor. It is commonly known as voltage and is measured in volts. A potential difference is necessary for the flow of electric current in a conductor.
How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.

What types of transistors are the following - BJT PCT UJT SBT FET GJT AJT DFT?
The BJT is the bipolar junction transistor, the PCT is the point contact transistor, the UJT is the uni-junction transistor, the SBT is the surface barrier transistor, the FET is the field effect transistor, the GJT is the grown-junction transistor, the AJT is the alloy-junction transistor, and the DFT is the drift field-junction transistor.
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".
