Electric circuit

Good morning, I found this book, “Introduction to Electric Circuits”; Dorf, Svoboda, 9th Edition, 2014. I know this text was made using \LaTeX, my concern is about to know how they got this circuit style. I noticed the editors used OrCAD Capture to design these circuits in order to make them easily and faster (also by looking at the inductor style in this example). I would like to know if anyone out there has had the same concern, circuitikz sometimes does not have enough power, and for instance, I like this current source more than the circuitikz's, with a thick straight triangle in the arrow instead of this one. You can easily distinguish them.

I hope I get some help, any advice is welcome. Thank you in advance.

    TikZ' own IEC standard shapes from its own circuit library has these shapes

    In addition to percusse's comment, you are always free to patch the circuitikz style and include your favorite arrow within the current source symbol. Nov 13, 2014 at 7:05

This is one way of doing it via circuitiz package. Two customized circuit elements are designed via macros called mycurrent and myswitch, hoping this will serve as a starting point.

enter image description here



\newcommand{\mycurrent}[2] % #1 = name , #2 = rotation angle
{\draw[thick] (#1) circle (12pt);
\draw[rotate=#2,line width=1pt]  (#1)  +(0,-6pt) -- +(0,6pt) coordinate(a1);
\draw[rotate=#2,thin] ($(a1)+(0,1pt)$) to [bend right=12] ++(2pt,-5pt);
\draw[rotate=#2,thin] ($(a1)+(0,1pt)$) to [bend left=12] ++(-2pt,-5pt);
\draw[rotate=#2] (#1) +(-0.58,0) coordinate(c)  +(0.57,0) coordinate (a)
 +(0,-0.5 )coordinate(b)
(a)node[above](a1){a} arc (0:-50:0.6)
(b)node[left] (b1){b} arc (-90:-0:0.4);
\draw [shorten >=-10pt] (c)node[below](c1){c}-- ($(a)!0.5!(b)$);
\draw[thick,red,->] (c) ++ (0.5,0.3)  to[bend left] ++(-0.5,-0.8)node[above=0.5cm]{\scriptsize$t=0$};

\draw (-1,0)node(o){} to[I=$6A$] (-1,2);      % default current

\draw (0,2) to[I,color=white,name=C1] (0,0);  % customized curent

\draw (-1,2) to[generic,color=white,name=S1] (3.5,2) to[I,color=white,name=C2] (5,2); %customized element
\draw (b) to[short,o-*] (b|-o);
\draw (-1,2) to[short,-o](c);
\draw (a) to[short,o-](3.5,2);

\draw (-1,0) to[short](5,0);
\draw (3.5,2) to[R=$4$,*-*] (3.5,0);
\draw (5,2) to[L, l=$\frac{1}{5}F$] (5,0);

  • I have no words. Just thank you. You have done a work even better than I would expect. :)

  • Would you please help me out doing the same to a controlled current source, @Jesse ? Thanks in advance.

  • OK, here is the myctrcurrent macro -- \newcommand{\myctrcurrent}[2] % #1 = name , #2 = rotation angle {\draw[thick] (#1) ++(0,-14pt) --++(12pt,14pt) --++(-12pt,14pt) -- ++(-12pt,-14pt)-- cycle; \draw[rotate=#2,line width=1pt] (#1) +(0,-6pt) -- +(0,6pt) coordinate(a1); \draw[rotate=#2,thin] ($(a1)+(0,1pt)$) to [bend right=12] ++(2pt,-5pt); \draw[rotate=#2,thin] ($(a1)+(0,1pt)$) to [bend left=12] ++(-2pt,-5pt); } Then change the first line of independent source into \draw (-1,0)node(o){} to[cI,color=white,name=C0,l=$6i_xA$] (-1,2); \myctrcurrent{C0}{0}

#RGB(10,123,183)  # bluish color

.PE           # Picture end

Convert to the .TEX (I can't paste it that has long lines) file then into add LaTeX file,


And display
