Help with drawing the following circuit diagram

Question

I'm just learning how to use circuitikz and I'm trying to draw the following circuit diagram

Here's what I've got so far

\begin{circuitikz}
  \draw (0,0) node[ocirc,ground]{$-m$}
  to[short] (1,0)
  to[R=$text$] (2,0) 
  to[short] (3,0)
  to[R=$text$] (4,0) 
  to[short] (5,0)
  to[R=$\ldots$] (6,0)
  to[short] (7,0)
  to[R=$text$] (8,0) 
  to[short] (9,0)
  to[R=$text$] (10,0) 
  to[short] (11,0)
  to[R=$\ldots$] (12,0)
  to[short] (13,0)
  to[R=$text$] (14,0) 
  to[short] (15,0)
  to[R=$text$] (16,0) 
  to[short] (17,0)
  to[short] (17,2) 
  to[V=$1V$] (0,2)
  to[short] (0,2)
  to[short] (0,0);
\end{circuitikz}

I'd really appreciate some help to resolve the following issues:

1. Adding nodes between the resistors with labels.
2. Making the whole thing fit on the page!
3. Having an ellipsis as the node (rather than having a resistor there like I do now)
4. Putting the leftmost label on the left rather than where it falls now.

Thanks!

\documentclass[margin=3mm]{article}
\usepackage{circuitikz}

\begin{document}
    \begin{circuitikz}
\draw (0,0) node[left=1mm] {$n$}     
                to [R=$+e_x-$,*-*]  ++ (1.5,0) node[below=3mm] {$-n+1$}
                to [R=$+e_x-$, -*]  ++ (1.5,0) node[below=3mm] {$-n+2$} coordinate[right=15mm]  (aux1)
      (aux1) node[below=3mm] {$-1$}
                to [R=$+e_x-$,*-*]  ++ (1.5,0) node[below=3mm] {$0$}
                to [R=$+e_x-$, -*]  ++ (1.5,0) node[below=3mm] {$1$}    coordinate[right=15mm]  (aux2)
      (aux2) node[below=3mm] {$n-2$}
                to [R=$+e_x-$,*-*]  ++ (1.5,0) node[below=3mm] {$n-1$}
                to [R=$+e_x-$, -*]  ++ (1.5,0) node[below=3mm] {$n$}    coordinate[above=15mm]  (aux3)
%
      (0,0) -- ++ (0,1.5)
            to [battery2, l=$+e_x-$,invert]   (aux3) -- ++ (0,-1.5)
      (0,0) -- ++ (0,-0.5) node [ground] {};
\path   (aux1) -- node {\huge$\dots$}    ++  (-1.5,0)
        (aux2) -- node {\huge$\dots$}    ++  (-1.5,0);
   \end{circuitikz}
\end{document}

gives

labels of resistors and battery in your sketch are not well readable. i read them as +e_x-, but i'm not sure in this. however you can easy change them to what you like to have.

Answer 2

nodes can be placed at coordinates between which resistors are drawn. Now node shape, label and placement of the label can be controlled.

The diagram can be scaled with the scale= option. Note that transform shape is also used along with it. Remove it and see what it is doing. ;)

See the example below:

\documentclass[border=3mm]{standalone}
\usepackage{circuitikz}
\usetikzlibrary{shapes}
\tikzset{elps/.style={fill,scale=0.5,ellipse, text width=1pt,text height=3pt}}
\ctikzset{bipoles/length=0.9cm}
\begin{document}
\begin{circuitikz}[scale=0.5,transform shape]
  \draw (0,0) node[ground]{};
  \draw (0,0) node[elps,label={[left=3mm]$-m$}]{}
  to[R=$text$] ++(2,0) node[elps,label={[below=3mm]$-m+1$}]{}
  to[R=$text$] ++(2,0) node[elps,label={[below=3mm]$-m+2$}]{}
  to[R=$\ldots$] ++(2,0)node[elps,label={[below=3mm]$1$}]{}

  to[R=$text$] ++(2,0) node[elps,label={[below=3mm]$0$}]{}
  to[R=$text$] ++(2,0) node[elps,label={[below=3mm]$-1$}]{}
  to[R=$\ldots$] ++(2,0) node[elps,label={[below=3mm]$m-2$}]{}

  to[R=$text$] ++(2,0) node[elps,label={[below=3mm]$m-1$}]{}
  to[R=$text$] ++(2,0) node[elps,label={[below=3mm]$m$}]{}

  to[short] ++(0,2) 
  to[V=$1V$] (0,2)
  to[short] (0,0);
\end{circuitikz}
\end{document}

Note that I have also replaced few absolute coordinates with relative coordinates using ++(x,y); removed few unwanted shorts and changed the bipoles length.
