Which equation governing a circular capacitor?
Using the recent advances in the asymptotic analysis of Fredholm integral equations of the second kind with finite support, here we study the one governing the circular capacitor, known as the Love equation. We find analytically many subleading terms in the capacitance at small separations.
How do you find the capacitance of a parallel-plate capacitor?
The electric field between the plates of a parallel-plate capacitor To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates.
How do you find the capacitance of a circular capacitor?
Our goal is to find the capacitance of a circular capacitor that consists of two thin coaxial conducting disks of unit ra-dius at the separation κ. The disks are held at equal potentials in the absolute value, ±V0/2, which guarantees equal charges on the two surfaces, ±Q. By the definition, the capacitance is given by C Q /V0.
Is there a second subleading term governing a circular capacitor?
Despite a large interest in the problem, one and a half century later, analytically was found only the second subleading term. Using the recent advances in the asymptotic analysis of Fredholm integral equations of the second kind with finite support, here we study the one governing the circular capacitor, known as the Love equation.
What does a capacitor mean in physics?
For a capacitor, it denotes the ratio between the charge on one of the plates and the potential difference between them. The capacitance purely depends on the geometry. The standard simplification in the textbooks is a parallel plate capacitor in a vacuum with the characteristic plate size much larger than their separation.
