# Calculate the Capacitance of Two Spheres based on Radius

The calculator will calculate the Capacitance of 2 spheres having same radius and separated by distance based on given values of permittivity of free space, relative permittivity and radius.

## Formula:

C=8πε_{o}ε_{r}a ln2

**Where,**

C = Capacitance of Two Spheres,

a = Radius,

ε_{o} = Permittivity of Free Space,

ε_{r} = Relative Permittivity
