Capacitors, Loss angle, Tan something, how to use it.
So we define a "loss angle", δ, such that the angle of the real capacitor''s impedance is θ = -(90-δ)° If you sketch that you will see that δ = atan(ωRC) Note that the tangent of the angle is R/X and not X/R because δ is measured with respect to the negative impedance axis, not the real resistance axis. Taking the tangent of both sides
nanoVNA
This will correlate to a phase angle of 90 degrees as measured by the VNA (positive for an inductor, and negative for a capacitor). This strategy places the impedance being measured within the nanoVNA''s abilities to measure accurately, and ensures that the measurement is performed well below the self resonant frequency of the component.

6 FAQs about [Using capacitor to measure angle]
What is a capacitive angle sensor?
The capacitive angle sensor are widely used in micro-nano driving control , , , , with the advantages of simple structure, high resolution, strong anti-interference ability and dynamic characteristics.
Do capacitive angle sensors have a performance simulation?
Although capacitive angle sensors have been extensively studied, their performance simulation is rarely reported. Without this simulation, when designing a capacitive angle sensor, some parameter adjustments require repeated processing, which increases design time and cost.
How do you test a capacitor?
Test setup for evaluating a capacitor as in Example 1. Set the function generator to output a 100 Hz sine wave with 1 Vpp amplitude at 50 Ω. (Note that the voltage measurement on the oscilloscope will be almost twice this amplitude since measurements are being made with 10 MΩ probes.)
Why does the capacitance change during the rotation of a sensor?
Although the angle changes on the gap, the actual capacitance did not change much, or during the rotation of the sensor, since the radial bounce of the axis, there is a tilt angle in the positive area of the two plates during the rotation, resulting in unstable voltage variation.
Can a real capacitor be measured as a separate component?
When we measure a real capacitor, the equivalent series inductance (ESL) will impact the capacitance reading, but we won’t be able to measure it as a separate, distinct component. The I-V method described in this application note is just one of many methods for measuring impedance. Others include the Bridge Method and the Resonant Method. Figure 2.
Can COMSOL Multiphysics be used for rotary capacitor angle sensors?
