The Junction Field Effect Transistor (JFET)exhibits characteristics which often make it more suited to a particular application than the bipolar transistor. Some of these applications are:
- High Input Impedance Amplifier
- Low-Noise Amplifier
- Differential Amplifier
- Constant Current Source
- Analogue Switch or Gate
- Voltage Controlled Resistor
It can be either a Bipolar Junction Transistor (NPN or PNP) or a Field Effect Transistor (N channel JFET, P channel JFET, N channel MOSFET, or P channel MOSFET).

BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
Transistor is a three terminal device. Its shape may differ with applications.
It's a junction gate field effect transistor that has it's bandwidth tuned to operate (amplify) in the radio frequency range.
JFET is a unijunction transistor.
Its a Transistor used in JFET (Junction Field Effect Transistor)
It can be either a Bipolar Junction Transistor (NPN or PNP) or a Field Effect Transistor (N channel JFET, P channel JFET, N channel MOSFET, or P channel MOSFET).
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.

Junction Field Effect Transistor are classified as hi impedance devices

Because the insulation between the gate and the channel is only a reverse biased PN junction. If this junction were to become forward biased the jfet would no longer operate as a transistor at those times.
1-BJT is bipolar while JFET is unipolar. 2-BJT has low input impedence while JFET has high input impedence. 3-JFET has low power discipation as compared to BJT. 4-JFET has low noise as compared to BJT. 5-BJT is current controlled while JFET is voltage controlled. 6-JFET is mostly used in digital circuits.
A: A FET has a very hi impedance it requires mostly potential as opposed to current like a transistor does,
