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.

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
#2 Kjell Magne Fauske, July 5, 2009 at 8:17 p.m.
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And noticed that “symbols”-option is obsolete.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}
#6 François, January 1, 2012 at 1:59 p.m.
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}

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.
#8 Dave, March 7, 2012 at 8:27 p.m.
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 https://ctan.org/pkg/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
