# Resistor Extraction

*Extraction*

## Description

Using this feature the resistance of a single arbitrary shape can be extracted. Four steps are required to do this:

Choose a polygon

Choose an input edge/port

Choose an output edge/port

- Enter material data in the dock windows

The resulting resistance will be displayed. Also the electrical field density is shown.

## Algorithm

The finite differences method is used to calculate electrical resistance. It is a two-dimensional calculation process. As three-dimensional parameter only the layer thickness from the LayerManager is used to calculate the square resistance from the specific resistance of the material. Any other 3-D geometry is not considered in the calculation. Any calculated resistances are for direct current only. No skin effects or other factors are considered.
