How to make in Bold the (+ and -) of vsource in tikzcircuit

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. — Community, Nov 12 '23 at 15:22
What the automatic comment means is that it would be helpful if you can post the full LaTeX code of a document that contains the example diagram. This would make it easier to reproduce and to test potential answers. — Marijn, Nov 12 '23 at 15:26

I suppose you are using circuitikz (because you tagged so --- would you please provide an example next time, or if my answer is not the one you are looking for?). Moreover, I suppose you are using standard fonts and pdflatex.

In that case, you can use the keys shown around page 75 in the (current) manual:

So, for example (I fixed the units also so that they use standard SI typesetting)

\documentclass[border=10pt]{standalone}
\usepackage[T1]{fontenc}
\usepackage[siunitx, RPvoltages, american]{circuitikz}
\ctikzset{bipoles/vsourceam/inner plus={\boldmath $+$}}
\ctikzset{bipoles/vsourceam/inner minus={\boldmath $-$}}
\begin{document}
\begin{tikzpicture}[]
    \draw (0,0) to[V, l=\qty{24}{\volt}] ++(0,3)
        to[R=\qty{5}{\ohm}] ++(3,0)
        to[R, l_=\qty{10}{\ohm}, v^=$V$]
        ++(0,-3) to[short, -*] (0,0) node[ground]{};
\end{tikzpicture}
\end{document}

Notice that, anyway, the bold plus and minus are, at least with standard math font, not so bold... you can have a look here for some suggestions, or, if you want to go really bold:

\documentclass[border=10pt]{standalone}
\usepackage[T1]{fontenc}
\usepackage[siunitx, RPvoltages, american]{circuitikz}
\usepackage{pifont}
\ctikzset{bipoles/vsourceam/inner plus=\ding{58}}
\ctikzset{bipoles/vsourceam/inner minus=\rotatebox{90}{\ding{121}}}
\begin{document}
\begin{tikzpicture}[]
    \draw (0,0) to[V, l=\qty{24}{\volt}] ++(0,3)
        to[R=\qty{5}{\ohm}] ++(3,0)
        to[R, l_=\qty{10}{\ohm}, v^=$V$]
        ++(0,-3) to[short, -*] (0,0) node[ground]{};
\end{tikzpicture}
\end{document}

If you also want to change the symbols in the voltage indication (but please, do not use pifont for that !), you can use the settings found on page 207:

I guess he want the plus and minus sign for the right side ‘resistor’ also in bold. — Tom, Nov 12 '23 at 19:02
@Tom not sure, but I added to the answer the relevant manual excerpt. — Rmano, Nov 12 '23 at 19:06
