Example: CircuiTikz - Easy electrical networks

Published 2008-11-03 | Author: Massimo Redaelli

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.

    Hi!

    Congratulations and thanks to the author by the package.

    How do I get the motors in the circuit? I have not found this symbol

    thank you very much

    Mary, you should ask Massimo Readelli about this. I'm sure that he can help.

    Hi,

    I had some problems with this example. First, I got an error message:

    ! LaTeX Error: Unknown option symbols' for packagecircuitikz'.

    Then I looked at the documentation: http://mirror.ctan.org/graphics/pgf/contrib/circuitikz/doc/latex/circuitikz/circuitikzmanual.pdf

    And noticed that "symbols"-option is obsolete. I removed it, but then I started having problems with those \micro\farad -stuff.

    How to fix:

    \usepackage[symbols]{circuitikz} changed to \usepackage[siunitx]{circuitikz}

    Add \SI{}{}, for every component. Like this:

    WRONG: [C, l=$10\micro\farad$]

    FIXED: [C, l=$\SI{10}{\micro\farad}$]

    Just figured out a simpler way: just edit the beginning of the file to:

    \documentclass{article}

    \usepackage[free-standing-units]{siunitx}

    \usepackage{circuitikz}

    \usepackage{tikz}

    \begin{document}

    And I would add that now (2012) the "free-standing-units" option is also obsolete.

    Now it works fine with this preamble:

    \documentclass{article}

    \usepackage{tikz} \usepackage{circuitikz} \usepackage{siunitx}

    \begin{document}

  • #7 Tiffany Hayes, February 10, 2012 at 11:40 p.m.

    So you still need to use the \SI command I noticed. Also, I keep getting units under other circuit parts (but no errors from LaTex). Is there any way to just move the labels, or do I just need to enlarge the size of my circuit? I'm using the code as above, but with the \SI inserted as described above.

    Hey, is there a way to create a caption above a resistor and the related value below the resitor?

  • #9 Anon, April 18, 2012 at 9:20 p.m.

    I don't see how to download the CircuiTikz files - the links are 404 not found and it looks as though Massimo Redaelli does not exist at the faculty list of the Dipartimento di Elettronica e Informazione (DEI) website. Could someone who has the packages let me know?

  • #10 Jannik, May 11, 2012 at 7:25 p.m.

    Try http://www.ctan.org/tex-archive/graphics/pgf/contrib/circuitikz/tex/latex/circuitikz or your Tex Live Manager

  • #11 Jeff Hein, May 31, 2012 at 2:51 a.m.

    This is simply amazing! Thank you so much for your hard work!

  • #12 Alex Mason, July 10, 2012 at 11:56 a.m.

    Hi all

    I have a slightly related issue with this to do with nodes.

    In the documentation it says to use things like o_o or _ to produce nodes on the ends of components. However LaTeX gives the error that it does not know the keys o_o or _.

    Perhaps they have been replaced or removed. Does anyone know?

  • #13 fred, September 14, 2012 at 6:30 p.m.

    Does anybody know if there is a circuit symbol for varistors,MOVs, or surge arrestors? Thanks

  • #14 Charlie, October 17, 2012 at 8:41 p.m.

    The links to the Circuitikz homepage are broken.

  • #15 Tony, June 26, 2013 at 3:16 a.m.

    The hollow circles at the end of a line is produced w/ -o (right), or o- (left), per the manual samples.

    Mr. Redaelli's circuitikz manual provides this URL for source, and also has useful examples, symbol list
