## Formula for Cylindrical Capacitor

The capacitance CCC of a cylindrical capacitor is calculated using the formula:

Where:

- ε0 is the permittivity of free space (8.854×10−12 F/m
- εr is the relative permittivity of the dielectric material between the cylinders.
- L is the length of the cylinders.
- a is the radius of the inner cylinder.
- b is the radius of the outer cylinder.

## Example Solve

Let’s consider an example where:

- Inner radius a=2 cma = 2
- Outer radius b=4 cmb = 4
- Length L=10 cmL = 10
- Relative permittivity εr=1

Using the formula:
