Trouble formatting circuitikz with wrapfig and enumerate

Question

I'm trying to format a basic circuit question, where a circuit diagram is placed to the right of the choices in a multiple choice question.

Currently, it looks like

I'm after something that looks like, e.g.

Unfortunately, I'm having trouble figuring out how to do this with the wrapfigure and enumerate environments. The circuit diagram is getting placed below the choices, rather than to their right. Any help would be much appreciated!

\documentclass{exam}
\usepackage{circuitikz} % for drawing circuit diagrams
\usepackage{wrapfig} % for wrapfigure environment
\usepackage{enumitem} % more options for enumerate command
% define enumerate command for new multiple choice question
\newlist{mcquestion}{enumerate}{1}
\setlist[mcquestion,1]{label={\bfseries\arabic{mcquestioni}.}, leftmargin=*, resume=mcquestion}
\def\remembered[#1]{\typeout{Call #1:\arabic{mcquestioni}}}
% define enumerate command for possible choices
\newlist{mchoices}{enumerate}{1}
\setlist[mchoices,1]{label={\bfseries\alph.}, wide=1cm, leftmargin=}
\begin{document}
\begin{mcquestion}
    \item In the circuit drawn in the figure, the ammeter has no resistance, and the battery has an e.m.f.~$\varepsilon$ and an internal resistance~$r$. Which of the following is correct?
\end{mcquestion}
\begin{mchoices}
    \item The current flowing through the ammeter is zero.
    \item The p.d. across the ammeter is zero.
    \item The potential drop \textbf{inside} the battery is zero.
    \item The energy dissipated in the whole circuit is zero.
\end{mchoices}
\begin{wrapfigure}{R}{0.5\linewidth}
\begin{circuitikz}[scale=2] \draw
    (0,1)   to[battery, l={$\varepsilon$, r}]   (1,1)
    (1,1)   --                                  (1,0)
    (1,0)   to[rmeter, t=A]                     (0,0)
    (0,0)   --                                  (0,1)
;
\end{circuitikz}
\end{wrapfigure}
\end{document}

Welcome. // Interesting question. Can you please add a screenshot of your current result? Thank you. — MS-SPO, Jun 26 '23 at 14:16
Unfortunately, wrapfig and any list-like environment are incompatible (see the first bullet point on the first page of wrapfig documentation). You are much better using explicit minipages for it. (BTW, it has nothing to do with circuitikz, it would happen the same with any figure content). — Rmano, Jun 26 '23 at 15:56

As I commented, wrapfig and list environments do not work well together, as noted by the manual (first page):

Although you can help it work, I think that in this case, explicitly using a minipage is better (I changed problem, which is undefined, to mquestion):

\documentclass{exam}
\usepackage{circuitikz} % for drawing circuit diagrams
\usepackage{wrapfig} % for wrapfigure environment
\usepackage{enumitem} % more options for enumerate command
% define enumerate command for new multiple choice question
\newlist{mquestion}{enumerate}{1}
\setlist[mquestion,1]{label={\bfseries\arabic{mquestioni}.}, leftmargin=*, resume=mquestion}
\def\remembered[#1]{\typeout{Call #1:\arabic{mquestioni}}}
% define enumerate command for possible choices
\newlist{mchoices}{enumerate}{1}
\setlist[mchoices,1]{label={\bfseries\alph.}, wide=1cm, leftmargin=}
\begin{document}
\begin{mquestion}
    \item In the circuit drawn in the figure, the ammeter has no resistance, and the battery has an e.m.f.~$\varepsilon$ and an internal resistance~$r$. Which of the following is correct?
\end{mquestion}
\begin{minipage}[t]{0.65\linewidth}
\begin{mchoices}
    \item The current flowing through the ammeter is zero.
    \item The p.d. across the ammeter is zero.
    \item The potential drop \textbf{inside} the battery is zero.
    \item The energy dissipated in the whole circuit is zero.
\end{mchoices}
\end{minipage}\begin{minipage}[t]{0.3\linewidth}
\begin{circuitikz}[scale=2, baseline=(A.center)] \draw
    (0,1)   to[battery, l={$\varepsilon$, r}, name=A]   (1,1)
    (1,1)   --                                  (1,0)
    (1,0)   to[rmeter, t=A]                     (0,0)
    (0,0)   --                                  (0,1)
;
\end{circuitikz}
\end{minipage}
\end{document}

Notice how I fine-tuned the vertical position of the circuit with the baseline option (this is from TikZ).

Many thanks! I've slightly adjusted the formatting for aesthetic reasons, which others may find helpful, adding \vspace{-1em} before \begin{minipage}{0.65\linewidth}\begin{mchoices} and \centering the circuit diagram. — nullgeodesic, Jun 27 '23 at 04:18
