Plotting circuits with circuitikz

Question

I have one small problem (I managed to draw what I needed, and for a first timer I'm very proud of myself XD). I need to draw image like this:

And what I managed to get is this:

So, the resistor can be changed probably by messing with American or European style, that's not a big problem. What is a big problem, is that I cannot get those nodes like in the first picture : Also how to get the ammeter and voltmeter properly aligned? The code is:

\begin{figure}[ht!]
\begin{center}
\begin{circuitikz}\draw
(0,0)to[sI] (0,4)
     to[R=$1\ k\Omega$,-*] (3,4) -- (5,4)
     to[voltmeter] (5,0) -- (0,0)
(3,4)to[ammeter] (3,2)
(3,0)to[Do,*-] (3,2)
(2,1)to[zDo](2,1)
;\end{circuitikz}
\end{center}
\end{figure}

Also, can I get the little lines in front and behind the Zener diode?

Answer 1

(answer to comments below)

Here is one solution. Note that the ammeter and voltmeter that you wanted aren't in circuitikz' set of components. To get around this I used the fact that all of the components and lines are tikz components and lines so that all of the stuff valid in tikz can be used. I created nodes with the appropriate info. In addition, I used the siunitx package to type the resistor. This way the units are correctly set. circuitikz has a siunitx option. To get the little lines with the diode : just use different starting and end points. My code is

\documentclass{minimal}
\usepackage{tikz}
\usetikzlibrary{arrows}
\usepackage{siunitx}
\usepackage{circuitikz}

\begin{document}

\tikzset{component/.style={draw,thick,circle,fill=white,minimum size =0.75cm,inner sep=0pt}}

\begin{circuitikz}[european]
\draw (0,2.5)node[left] {$+$} to[short,o-] (0,4)
      to[R=\SI{1}{k\ohm},-*] (3,4) to[short] (5,4)
      to[short] (5,2) node[component]{V} to[short] (5,0)
      to[short] (0,0) to[short,-o] (0,1.5)node[left] {$-$};
\draw    (3,4) to[short] (3,3) node[component]{A} to[short] (3,2)
        (3,0) to[Do,*-] (3,2)
        (2,0.5) to[zDo] (2,1.5);
\end{circuitikz}

\end{document}

The result is

About the little circles : the key is not to use the -- in the path (as in my initial solution), but rather to use the circuitikz path styles. For what you want, you need to enter to[short,o-]. All this is in the new version of the code..

For the + and -, just add nodes at the appropriate place. I modified the code of my example for this (not the picture thought).
