Question

the channel resistance of a jfet is a constant.
select one:
○ true
○ false

Explanation:

The channel resistance of a JFET (Junction Field - Effect Transistor) is not constant. It depends on the gate - source voltage ($V_{GS}$). As the gate - source voltage changes, the width of the conducting channel in the JFET changes, which in turn changes the channel resistance. For example, when the magnitude of the negative gate - source voltage (for an n - channel JFET) increases, the channel width decreases, and the channel resistance increases. So the statement that the channel resistance of a JFET is a constant is false.

Answer:

False
