A Jfet stands for junction field effect transistor. It is a transistor also known for being the simpleist field effect transistor. The basic construction contains has three parts the P-type input the n-type input and a depletion layer.
A Jfet works by applying voltage to the drain of the jfet. A jfet will then conduct across from drain to source.
• High Input Impedance Amplifier. • Low-Noise Amplifier. • Differential Amplifier. • Constant Current Source. • Analog Switch or Gate. • Voltage Controlled Resistor. • JFET as a Switch • JFET as a Chopper • JFET as a Current source • JFET as a Amplifier • JFET as a Buffer
JFET is a unijunction transistor.
The answer depends on what the requirements for the basic construction are.

No, jfet works only in depletion mode.
no
It depends on the topology of the circuit in which the JFET is operating.

FET is a field effect transistor, abbreviated to FET. There are two basic types of FET: a junction FET abbreviated to JFET and an insulated gate FET , abbreviated to IGFET. The most common type of IGFET is a metal-oxide silicon FET, Known as a MOSFET. Modern microprocessors may contain tens of millions of MOSFETs.
