Depletion Region of reverse bias diode

[Sandeep Km]

I would like to know if we place a capacitor external in parallel with the reverse biased diode what would happen to depletion region?
whether it increase or decrease?

 

[crutschow]

Since the capacitor is in parallel with the diode and the reverse bias voltage would not change (assuming the reverse bias is provided by some voltage source), why would you think the capacitor would affect the depletion region?

Is the capacitor charged to a different voltage than the
diode? Is this perhaps a charge-division homework problem?
