For a diode the transition capacitance was 10pF. The depletion width changed from 1µm to 10 µm. All other conditions remain unchanged. The new diode capacitance is __________ Correct Answer 1pF

The equation of transition capacitance = ƸA/W Where Ƹ = permittivity of the material of diode, W = depletion width A = area of cross section Since depletion width increased 10 times and all other quantities are the same, the capacitance decrease by 10 times.
