The input control parameter of a JFET is __________________?
Correct answer: A. gate voltage
- A. gate voltage
- B. source voltage
- C. drain voltage
- D. gate current
Explanation
The gate-to-source voltage is the input control parameter of a JFET because it controls the depletion-region width and therefore the channel current. Gate current is ideally negligible and is not the controlling input.
