Option add a node to any point in a circuit?

Question

Was wondering if there is a way to add a node to a circuit drawn with "circuitikz" at any point. However, if I would, for example, change the bottom-left node of my circuit to point downwards instead? Is there an option to just move the component on the line or add a line with a node? I was lucky this time since I could organise, but curious to know this for another time.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[siunitx]{circuitikz}
\begin{document}
\begin{figure}
    \centering
\begin{circuitikz}[scale = 1.5]
\draw
(-4,0) to[R,l=$\mathcal{R_1}$,o-o] (2,0)
(0,0) to[R,l=$\mathcal{R_2}$,-] (0,2)
(-4,2) to[R,l=$\mathcal{R_3}$,o-o] (2,2)
(-2,2) to[R,l=$\mathcal{R_4}$,-] (-2,4)
(-4,4) to[R,l=$\mathcal{R_5}$,o-o] (2,4)
(0,4) to[R,l=$\mathcal{R_6}$,-] (0,6)
(-4,6) to[R,l=$\mathcal{R_7}$,o-o] (2,6)
(-2,0) to[american current source,-,l=$\Phi_1$] (-2,2)
(-2,4) to[american current source,-*,l=$\Phi_2$] (-2,6)
;
\end{circuitikz}

Not related, but I suppose you want \mathcal{R}_1, there are no numbers in mathcal font. And probably you'll need \usepackage[T1]{fontenc} https://tex.stackexchange.com/questions/664/why-should-i-use-usepackaget1fontenc — Rmano, Feb 18 '22 at 11:07

I am not really sure if I understood your question --- if not, please sketch what you need. Anyway, if for nodes you mean the filled poles (that's the name used in the manual, to avoid confusion with TikZ nodes), you can put them where you need with

\node[circ] at (3,3) {};

or along a path

\draw ... (3,3) node[circ]{} ...

Another option is to use a wire or an open with poles:

\draw (0,0) to[short, o-*] (1,1) to[open, *] (2,2);

Anyway, I would draw it like this; using relative coordinates and coordinates names you can then stretch and shrink things just changing one number.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[siunitx]{circuitikz}
\begin{document}
\begin{figure}
    \centering
\begin{circuitikz}[scale = 1.5, american]
\draw
(0,0) coordinate(start) 
    to[short, o-] ++(0,1) -- ++(2,0) coordinate(phi1r1)
    to[R,l=$\mathcal{R}_1$,-] ++(2,0) coordinate (r1r2)
    to[short, -o] ++(2,0) coordinate(bot1)
    % phi
    (phi1r1) to[I, l=$\Phi_1$, -] ++(0,2) coordinate(phi1r3)
    % node to the right above the first one
    to [short, -o] (phi1r3 -| start) % perpendicular coords
    (phi1r3) to[R,l=$\mathcal{R}_3$,-] (phi1r3 -| r1r2)
    to [short, -o] (phi1r3 -| bot1)
    (r1r2) to[R,l=$\mathcal{R}_2$] (phi1r3 -| r1r2)
;
\end{circuitikz}
