Explain Depletion Region.

1.	Explain Depletion Region.
Answer» When a POSITIVE voltage is applied across GATE, it causes the free holes (positive CHARGE) to be repelled from the region of substrate under the Gate (the channel region). When these holes are pushed down the substrate they leave BEHIND a carrier-depletion region. When a positive voltage is applied across Gate, it causes the free holes (positive charge) to be repelled from the region of substrate under the Gate (the channel region). When these holes are pushed down the substrate they leave behind a carrier-depletion region.
