A JFET is also called ________ device.
Unipolar
Because current conduction depends predominantly on only one type of charge carrier (either electrons or holes), the JFET is classified as a unipolar device . The difference in charge carrier reliance is the fundamental reason for their classification as unipolar and bipolar, respectively.
