- Title: Circuitikz
- Grid: 2x2
CircuiTikz_ is a set of LaTeX macros designed to make it easy to draw electrical networks in scientific publications. It provides a convenient syntax based on to-paths to place the various components.
The examples below are from the `CircuiTikz examples page`_. The author of CircuiTikz_ is `Massimo Readelli`_.
To run the examples you need to `download and install`_ the CircuiTikz_ files first.
- Note*. The circuits library available in the CVS version of PGF is inspired by CircuiTikz_.
