Field-Effect Transistors (FETs)

If an n-channel JFET has a positive drain voltage and the gate-source voltage is zero, the drain current will be

• zero

  
  

• IDSS

  
  

• IGSS

  
  

• none of the above

  
  

For a JFET, two voltages with the same magnitude but opposite signs are

• VD and Vp

  
  

• VD and VS

  
  

• VGS(th) and Vcutoff 

  
  

• Vp and VGS(off)

  
  

A set of characteristic curves for a JFET are shown. The blue lines represent different values of
