Topic: Electronic Devices and Circuits

For two identical n-channel JFET's connected in parallel as shown in figure below, the pinch-off voltage of equivalent JFET is

  • A. doubled
  • B. becomes half
  • C. remains same
  • D. none of the above

Answer: A. doubled

Explanation: Note: According to the official answer key, the answer is option (a). However, the detailed explanation in the source document states: "When the two identical JFETs are connected in parallel, then pinch-off voltage of equivalent JFET is some as that of individual JFET", which corresponds to option (c). The JSON extraction captures the options exactly as presented.
