Increasing reverse bias voltage applied to p-n junction diode ……..

Options

A. depletion capacitance and resistance of diode of diode increases.
B. depletion capacitance and resistance of diode of diode decreases.
C. depletion capacitance decreases but resistance of diode increases.
D. depletion capacitance increases but resistance of diode decreases.

Answer

C

Explanation

depletion capacitance decreases but resistance of diode increases.
On incresing reverse bias voltage in p-n junction diode the width of depletion barrier increases.
Therefore according to formula `C prop (1)/(d)` value of capacitance increases.
Now according to `V=(Q)/(C )` as C decreases V increases. So resistance in reverse bias from `(r_(rb)=(DeltaV)/(DeltaI))` increases.
