The electrostatic capacitance of ceramic capacitors is generally measured using an LCR meter. 2. Measurement principle The typical measurement system of LCR meters is the "automatic balancing bridge method," such as shown in the figure below. The measurement principle is as follows.
The capacitance capacitor is the ratio of the magnitude on two bodies to the potential between the bodies. C in Farads, Q in coulombs, V in volts. feel these are the most important concepts to grasp in order to make scientific electrostatic measurements. I will give two examples to show how these laws are important in electrostatic measurement.
The capacitive measuring principle is based on the method of the operation of a capacitor. A capacitor is formed by two differently charged electrodes isolated from each other. Applying an alternating current between the electrodes will create an electric field.
From the theory of the electrostatic induction, a charged particle and an electrostatic sensor are regarded as an equivalent capacitor, as shown in Fig. 1. The movement of the charged particle with reference to the electrode changes the distance between the two plates of the capacitor and hence the capacitance value .
This is why electrostatic induction is also termed as capacitive coupling in many references and thus an electrostatic sensor is equivalent to a capacitive sensor in such a case. In principle, both electrostatic sensors and capacitive sensors work on the fluctuation of the electric field around the sensing electrode.
When a sensor works on electrostatic induction, the sensing principle may be explained in terms of an equivalent capacitive sensor. This is because that the charged object can be modelled as a plate of a capacitor whilst the electrode itself is modelled as the other plate, as shown in Fig. 1.
