I'm trying to write quite a simple document here but I'm having a frustrating problem with my tabular. Here's my code:
\documentclass[a4paper,10pt]{article}
%\documentclass[a4paper,10pt]{scrartcl}
\begin{document}
\begin{itemize}
\item[a)]\mbox{}\\%using this to go to the next line
\begin{tabular}{|l|c|c|}
\hline
& \textbf{A1 Configuration Série} & \textbf{A2 Configuration Parallèle} \\ \hline
\(\Delta\)V de la source : & 210V & 120V \\ \hline
I fourni par la source : & 10A & 20A \\ \hline
P dissipé par dans le radiateur : & 2000W & 2000W \\ \hline
Temps de fonctionnement : & 100s & 100s \\ \hline
Énergie livrée au radiateur : & 200 kJ & 200kJ \\ \hline
Énergie fournie par la source: & 210kJ & 240kJ \\ \hline
\end{tabular}
Text here should be indented as if there was no table.
\end{itemize}
\end{document}
The problem is that it gives mme this error :
Overfull \hbox (92.27675pt too wide) in paragraph at lines 5--16
What I understand from this error is that my tabular is too wide. I've tried to resize the comlums with p{2.5cm} but it did raise me another error. I think the problem is caused by the indentation of the item I use. If I could set the table out of the indent, but keep the rest inside of it, that would be great.
I've heard talking about \makebox but it doesn't seem to be supported in my environment, I use Kile on linux, or if it requires a special package.
UPDATE
I got a second question here, and I just ask for explanation, because I suppose this is something fairly easy to fix. If I use this table, after that paragraph I get the same overfull warning :
\item[c)]
En regardant le tableau d'efficacité ci-dessous, on observe que le \%
d'efficacité diminue lorsque l'on passe d'une configuration en série
vers une configuration en parallèle.
\begin{table}[h]
\begin{tabular}{|l|c|c|c|c|}
\hline
& \textbf{A1} & \textbf{A2} & \textbf{B1} & \textbf{B2} \\ \hline
\textbf{\% d' efficacité :} & 95.24\% & 83.33\% & 95.24\% & 83.33\% \\ \hline
\end{tabular}
\end{table}
\end{itemize}
Gives me this warning :
Overfull \hbox (10.11162pt too wide) in paragraph at lines 138--141
I don't think the problem is the table here, because if I get rid of it, there's still a warning. Why can't TeX render a simple paragraph like this without considering it is tool large? I'm quite new to LaTeX and I don't get this. The render is ok in my PDF.

The excessive width of the table is due to the headers of columns 2 and 3; you can divide it in three rows (unfortunately "Configuration" is too long a word):
