# Capacitance calculation

## 1. pair

If you wish to calculate shieldless construction, set the shield radius to
0 or large enough to conductor spacing.

## 2. coaxial cable

Input necessary parameters at any one of constructions then press 'compute'
button.

This program computes capacitances analytically for most common construction.
For more general case, we must use numerical methods.

The inductance at high frequency for high conductivity conductor can be
calculated by the following method.

L = e/C/c^2
where
L = (DC) inductance (H/m)
e = effective relative dielectric constant
C = capacitance (F/m)
c = the velocity of light in vacuum (2.998e8 m/s)
