How do the JFET and BJT behave differently in switching applications?
What will be an ideal response?
In the BJT, the positive alternation of the AC voltage from the function generator forward biases the BJT, causing current to flow. In the JFET, the negative alternation of the AC voltage reverse biases the JFET, which stops the flow.
