A JFET has high input impedance because A. It is made of semiconductor material. Input is reverse biased. Of impurity atoms. None of the above.
- Definition: JFET is the shortened form for J unction F ield E ffect T ransistor. It is a 3 terminal semiconductor device in which current conduction takes place only due to the flow of majority charge carriers. Thus, it is a unipolar transistor. The 3 terminals of the JFET are source, drain and gate.

- Oct 20, 2019 A JFET or Junction Field Effect Transistor is a transistor that classified under the category of FET. These are known for its voltage-controlled transistors where it doesn’t depend on the current for biasing. These consist of source, gate and drain as its terminals. This transistor comes under unipolar devices.
