What is a Cylindrical Capacitor Calculator?

A Cylindrical Capacitor Calculator computes the capacitance of a cylindrical capacitor, which consists of two coaxial cylindrical conductors separated by an insulating material (dielectric). The capacitance is given by:

where:

C = Capacitance (Farads)
ε = Permittivity of the dielectric
L = Length of the capacitor
R1 = Inner cylinder radius
R2 = Outer cylinder radius
