To measure the internal resistance accurate the channel 2 probe must be placed as close as possible at the capacitor. The resistor Rs must have approximately the same value as the impedance of the capacitor. De first method describes the measurement of small capacitors whereof the series resistance is negligible. Fig. 5: Mathematical model.
Another way to measure the capacitance is to include the unknown capacitor in a resonance circuit. The accuracy is directly dependent on the used reference inductor. Inductors with a small tolerance are rare and expensive. Fig. 11: Resonance method measuring arrangement for capacitors.
The proportionality coefficient capacitance of the capacitor. Its unit is FARAD F1: For a parallel-plate capacitor in a vacuum the capacitance is exclusively determined by the geometry of its arrangement. It is directly proportional to the area A of the plate and inversely proportional to the dis-tance d between the plates:
The capacitor to test is directly connected to the output terminals of the function generator who's delivering a squarewave voltage. The voltage across the capacitor is measured with an oscilloscope.
Parallel to the capacitor under test is the probe connected represented by the capacity Cp and the ohmic resistance Rp. The probe capacity Cp and the unknown capacitor Cx are taken together as one replacement capacity C. Because Cp (and also Rp) are known is it easy to figure out the unknown capacity. The current is measured with the aid of Rs.
The second method describes a measurement that is suitable for measuring on larger capacities and can also determine the internal series resistance (ESR). This method is thus mainly suitable for measuring on electrolytic capacitors. Figure 8 shows the mathematical model with the associated vector diagram in figure 9.
