4 FAQs about [Rotating capacitor plates]

What is a plate capacitor?

Plate capacitor with a voltage between the two electrodes. The distance between the electrodes is and the area of an electrode is . In between is a dielectric material . A plate capacitor usually consists of two round or rectangular conductive plates (also called Electrodes ). These have an area and are located at a distance from each other.

What is the potential of a plate capacitor?

The potential in the plate capacitor decreases linearly from the positively charged to the negatively charged plate. To express the electric field using the known voltage , the spatial derivative of the potential (gradient equation) is used (in the one-dimensional case):

How much capacitance should a tunable capacitor have?

Anywhere from 1% to 20% of the maximum capacitance. Check the data sheet. A tunable (rotating) capacitor consists of plates that are spaced apart by some measure. The spacing is what derives a given capacitance. By rotating extra plates in-between the stationary plates you reduce the spacing, thus changing the capacitance.

What is the maximum value of capacitance?

The MAXIMUM value of capacitance is normally what is specified for variable capacitors. Many makers also specify a minimum value range, which is less predictable. But in all cases the minimum value is not zero. In many cases the minimum is between 5% and 10% or the maximum. Is the question asking for a number? Or an explanation of the concept?
