Quickly calculate the capacitance of a cylindrical capacitor. Our tool uses the fundamental formula involving inner and outer radii, length, and the dielectric constant, providing accurate results for electrical engineering and physics applications. Understand the factors influencing capacitance.
Formula:
The capacitance (C) of a cylindrical capacitor is given by:
C = (2 × π × ε0 × εr × L) / ln(R2 / R1)
Where:
- C = Capacitance (Farads)
- π = Pi (approximately 3.14159)
- ε0 = Permittivity of free space (8.854 × 10-12 F/m)
- εr = Relative Permittivity (dielectric constant) of the dielectric material
- L = Length of the capacitor (meters)
- R1 = Inner radius of the conductor (meters)
- R2 = Outer radius of the conductor (meters)
- ln = Natural logarithm
