Re: measuring Capacitance or Inductance


 

Hi,
Roger have shown two plots with increase of capacitance with frequency, as the leads become longer the capacitance seems grows. It is caused by inductance but as I understand the model of real capacitor, the series capacitance extracted from it should not change. Should it be a influence of series inductance on measurement accuracy? I mean with the frequency increase the inductance impedance becomes much larger than the capacitance so we are getting bigger ratio between of them destroying the capacitance measurement?
