[Tex/LaTex] Drawing a Power Flow arrow in circuitikz

circuitikz

Is it possible to draw a power flow arrow in circuitikz?

I'd like to draw an arrow point away from the voltage source on the right that indicates the flow of power towards the left.

What I'm after is not a current arrow, but a larger arrow that sits above the circuit instead of on the wire.

Thanks in advance!

\begin{circuitikz} \draw
(0,0)   to [sV, l=$V_{\text{upstream}}$] (0,2)
        to [R, l=$R$] (2,2)
        to [L, l=$X_l$] (4,2)
        to [sV, l=$V_{\text{DG}}$] (4,0)
        -- (0,0);
;\end{circuitikz}

You can use the \draw command from TikZ to place the arrow at the desired location:

\documentclass{article} 
\usepackage{amsmath}
\usepackage{circuitikz}

\begin{document}

\begin{circuitikz} \draw
(0,0)   to [sV, l=$V_{\text{upstream}}$] (0,2)
        to [R, l=$R$] (2,2)
        to [L, l=$X_l$] (4,2)
        to [sV , l=$V_{\text{DG}}$] (4,0)
        -- (0,0);
\draw[-latex] (2.5,0.5) -- (1.5,0.5);
\end{circuitikz}

\end{document}

I too find the circuitikz documentation a bit lacking, but you learn a lot from inspecting the examples. A quick [circuitikz] search on the site will lead you to more examples. Moreover, a few additional circuitikz examples are available at texample.net.

Regarding spacing, my main piece of advice (which applies to any vector-graphics package, really) is to parameterise everything at the beginnning; refrain from using "magic numbers". Your circuit will be far easier to adjust; moving things around will be a breeze. See below.

\documentclass[convert = false]{article}
\usepackage[american]{circuitikz}
\begin{document}
\begin{circuitikz}[scale=2]
    \def\xPortLeft{0}
    \def\yTerminalBottom{0}
    \def\yL{1.5}
    \def\xL{1}
    \def\xR{1.75}
    \def\xC{2.25}
    \def\xPortRight{3}
    % left loop
    \draw                               (\xPortLeft,\yL)
            to[L=$L$, o-]               (\xL, \yL)
            to[R=$R$]                   (\xR, \yL)
            to[short]                   (\xC,\yL)
            to[C, l_=$C$,*-*]           (\xC,\yTerminalBottom)
            to[short,i=$i(t)$]          (\xPortLeft,\yTerminalBottom)
            to[open,v^>=$v_1(t)$,o-o]   (\xPortLeft,\yL);
    % right branch
    \draw                               (\xC,\yL)

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

Code

\documentclass[border=10pt]{standalone}  
\usepackage{tikz}
\usepackage[american,siunitx]{circuitikz}
\usetikzlibrary{calc,positioning}


\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);
}
%
\newcommand{\myswitch}[2]{
\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$t=0$};
}

\begin{document}  
\begin{circuitikz}
\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
\mycurrent{C1}{0}

\draw (-1,2) to[generic,color=white,name=S1] (3.5,2) to[I,color=white,name=C2] (5,2); %customized element
\myswitch{S1}{0}
\mycurrent{C2}{-90}
\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);
\end{circuitikz}

\end{document}
