C) an oscillator.
D) a regulator.

Question

Quizplus · Accepted Answer

When the JFET operates in the ohmic region or cutoff region, its drain current is very low, and it acts like an open circuit. Therefore, it can be used as an analog switch to connect or disconnect a circuit. This property of JFET makes it suitable for applications like amplifier switching, signal routing, and analog multiplexing. However, it cannot perform well as a linear amplifier, oscillator, or regulator in these operating regions.
