or ρs1=−ε1E. Similarly, in medium 2 ρs2=−ε2E. Thus, the E fields will be the same in the two dielectrics, but the charge densities will be different along the two sides of the inner conducting cylinder. Since the same voltage applies for the two sections of the capacitor, we can treat them as two capacitors in parallel.
A cylindrical (or coaxial) capacitor is made of two concentric metallic cylinders. Let the radius of the inner cylinder be ri and ro for the outer one. In-between the cylinders are two media with different relative permittivities ε1 and ε2. The two boundaries between these media may also be radial, see schematic on the right.

This web page deals with the capacitance of Coaxial Cable and Cylindrical Capacitors because both consist of a circular conductor, inside another circular conductor. The difference is that Coaxial Cable usually has a center conductor that is made up of solid or stranded wire and a solid dielectric material.
What is the capacitance of a cylindrical capacitor with just one dielectric inside? How can we use this result to calculate the capacitance of the given device using the filling fractions αi? This problem can be solved fastly if we remember the boundary conditions of the electric field E and the electric displacement field D.
Capacitors have many important applications in electronics. Some examples include storing electric potential energy, delaying voltage changes when coupled with resistors, filtering out unwanted frequency signals, forming resonant circuits and making frequency-dependent and independent voltage dividers when combined with resistors.
