# Calculate the Capacitance of Circular Solid Cylinder based on Radius

The calculator will calculate the capacitance of circular solid cylinder based on the given values.

Permittivity of Free Space (εo),Relative Permittivity (εr),radius and length. Capacitances are the storage device for electrical charge.

The circular solid cylinder's surface shaped by the points at a fixed distance from a given line segment, the axis of the cylinder.

The capacitance for cylindrical or spherical conductors can be calculated by applying Gauss' law.

## Formula:

C≃[8+4.1(l/a)^{0.76}]ε_{o}ε_{r}a

**Where,**

C = Capacitance of Circular Solid Cylinder,

a = Radius,

ε_{o} = Permittivity of Free Space,

ε_{r} = Relative Permittivity,

l = Length
