Capacitance*

Capacitance is the ability of a conductor or a system of conductors to store electric charge when a voltage is applied between them. Capacitance depends on conductor geometry, spacing between conductors, and dielectric properties of surrounding materials.

Capacitance calculation is required for analysis of capacitors, cable systems, capacitive sensors, PCB conductor layouts, and transmission lines. Analytical formulas are often insufficient for practical geometries involving complex dielectric arrangements or multiple conductors.

In QuickField, capacitance calculation is usually performed using the Electrostatics package.
