`C = 4 pi epsilon_r epsilon_0 "R" `

Enter a value for all fields

The **Capacitance of a Spherical Shell** calculator computes the capacitance of a single spherical shell.

**INSTRUCTIONS:** Choose your preferred units and enter the following:

- (
**R**) - the radius of the sphere - (
**ε**) - the Dielectric Constant of materials between cylinders_{r}

**Capacitance: **The capacitance (C) is returned in Farads. However, this can be automatically converted to other capacitance units via the pull-down menu.

The calculator uses the formula:

C = `4pi * epsilon_r * epsilon_0 * R`

where:

- (
**R**) is the radius of the sphere - (
**ε**) is the Dielectric Constant of materials between the shells. For more information on the Dielectric Constant, a.k.a. Relative Permittivity, of the material between the shells. For more info, click here. To see common dielectric constants, CLICK HERE._{r} - (
**ε**) Is the constant for the Permittivity of a Vacuum (8.85418782E-12 F/m)_{0}
