通過基本定義和有關名牌值進行了計算和分析，認為在正負極限檔，外加串聯調壓變的阻抗值相對額定檔的偏差很小，所以可不必在意這種變壓器整體阻抗的偏差值。With sufficient forward bias, the diffusion capacitance can easily exceed the space charge region capacitance.
當正向偏壓足夠高時，擴散電容很容易超過空間電荷壓電容。The displacement current mechanism is operative only for capacitors under reverse bias or very weak forward bias conditions which maintain a space-charge layer.
