Can a step-up method be used to calibrate a decade capacitor?

capacitance difference. An excellent description of a step-up method applied to tbe calibraLion of decade capacitors for both capacitance and dissipation factor has been described by Ford and AstbUl'Y of the British National Physical Laboratory .

Can a capacitor have the same capacitance and rated voltage?

Use a capacitor with the same capacitance, and the same or higher voltage rating. Also, Q Q is charge, and although it is the product of voltage and capacitance, you must use the applied voltage, not the rated. I figured it couldn't be so simple...and I guess I was mixing up my terms. Thanks! I'll accept your answer as soon as the site lets me.

Does voltage factor into capacitance?

The voltage is the maximum the capacitor can withstand before the dielectric breaks down, and does not factor into the capacitance (measured in farads, F F). Use a capacitor with the same capacitance, and the same or higher voltage rating.

How to calibrate a val'iable capacitor by step-up methods?

a val'iable capacitor by step-up methods. If the variable air capacitor, X, having a range from 100 to 1,100 pf, is to be calibrated at every 100-pf division mark, it is necessary to have a fixed air capacitor, S, of approximately 100 pf that can be connected in parallel with the variable capacitor under test in a precisely repeatable manner.

Can a step-calibration method be used to calibrate a variable capacitor?

6. Conclusion Step-calibration methods can be employed for the calibration of variable capacitors. The few neces sary items of equipment are generally available in any electrical measurements laboratory.

What is the universal equivalent circuit of a capacitor?

Figure 1 shows the universal equivalent circuit of a capacitor: RESR = equivalent series resistance in ohms. This is the real part of the impedance that produces losses via heat generation C = capacitance value in Farads. The reactance of this component is XC = 1 / 2πfC L = inductance in Henrys. The reactance of this component is XL = 2πfL
