Please consider the following MWE:
\documentclass[border={1mm}]{standalone}
\usepackage[europeanresistors]{circuitikz}
\begin{document}
\begin{circuitikz}
\draw (0,0)to [R,l={{{{\rotatebox[origin=c]{-90}{$+\;\; v_2\;\; -$}}}}},o-o](0,-3);
\end{circuitikz}
\end{document}
This is the output:
But I prefer the following output:
v
and thevoltage shift
and other voltage positioning options (see the manual). Otherwise, name the component and put nodes manually near the appropriate anchors... Will write a possible solution tomorrow, if nobody does it.
