At cut-off, the JFET channel is ___________

At cut-off, the JFET channel is ___________ Correct Answer completely closed by the depletion region

At cut off, the JFET channel is completely isolated by the depletion region. Gate connection is completely isolated from the main current carrying channel. At cut-off, VGS is sufficient to cause the JFET to act as an open circuit as the channel resistance is at maximum.
