Question

Depletion width and depletion capacitance of an abrupt junction

Answer 1

The capacitance at the depletion region changes with the change in applied voltage. When reverse bias voltage applied to the p-n junction diode is increased, a large number of holes (majority carriers) from p-side and electrons (majority carriers) from n-side are moved away from the p-n junction.

Answer 2

$\huge\red{\ddot\smile}$Ans.

Depletion Capacitance. The depletion layer capacitance. per unit area is defined. Where dQ is incremental charge per unit area as for an incremental charge per unit voltage. dV.
