# Drawing a Power Flow arrow in 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.

\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}

Not quite, sorry, I should've been more specific. I'm after a larger arrow that sits above the circuit. Thanks though! Just edited the question to clarify. –  Fabian Tamp May 17 '12 at 4:18
@Fabian: I've updated my answer. Is something like that waht you need? –  Gonzalo Medina May 17 '12 at 4:26
