Cylindrical Capacitor Calculator  

Permittivity :
ε = Cln (b/a)/2πL
Length of Conductors :
L = Cln(b/a)/2π ε
Outer Conductor Diameter :
b = ae (2πL/C)
Inner Conductor Diameter :
a = b/e (2π L/C)
Where,
C = Capacitance,
ε = Permittivity,
L = Length of Conductors,
b = Outer Conductor Diameter,
a = Inner Conductor Diameter.
Example:
Calculate the capacitance for the cylindrical capacitor by the given details.
Permittivity (ε) = 5 F/m
Length of Conductors (L) = 4 m
Outer Conductor Diameter (b) = 3 m
Inner Conductor Diameter (a) =2 m
Solution:
Apply Formula:
C = 2π εL/In ( b/a)
C = 2*3.14*5*4/ (3/2)
C = 309.77 F
Capacitance (C) = C = 309.77 F
