Formulas

Capacitance: C = (2πε₀ε_r) / ln(b/a)

Inductance: L = (μ₀μ_r) / (2π) * ln(a/b)

Where:
ε₀ = Permittivity of free space
ε_r = Relative permittivity of the dielectric
μ₀ = Permeability of free space
μ_r = Relative permeability of the core material

Coaxial Cable Capacitance and Inductance Calculator 使用指南

Learn how to use the Coaxial Cable Capacitance and Inductance Calculator and understand its working principles.

How to Use

  1. Enter the inner conductor radius (a) and outer conductor radius (b) in meters.
  2. Click the "Calculate" button to compute the capacitance and inductance.
  3. The results will be displayed in Farads (F) for capacitance and Henrys (H) for inductance.

Understanding the Formulas

The capacitance and inductance of a coaxial cable depend on the dimensions of the conductors and the properties of the dielectric material between them. The formulas used are derived from electromagnetic theory and are valid for a coaxial cable with a uniform dielectric.
