The pinch-off voltage in a JFET is analogous to _____________ voltage in a vacuum tube?
Correct answer: C. grid cut off
- A. anode
- B. cathode
- C. grid cut off
- D. none of the above
Explanation
The JFET gate voltage that cuts off channel current performs the same basic function as the grid-cutoff voltage in a vacuum tube. Anode and cathode voltages do not control the tube current in this analogous way.
