\title{Current-voltage characteristic of a resistor}
\author{Full Name \\ Group: ...}

\begin{document}
\maketitle

\section{Objective}
Determine the resistance $R$ from the current-voltage characteristic (Ohm's law).

\section{Theory}
\begin{equation}\label{eq:ohm}
  U = R\,I
\end{equation}
The resistance is the slope of the line $U(I)$.

\section{Setup and equipment}
Power supply, ammeter, voltmeter (state the accuracy classes in the report).

\section{Procedure and results}
The $U(I)$ characteristic is shown in Figure~\ref{fig:reg} (least-squares fit - \emph{Lab tools} panel).

\section{Data analysis and uncertainty}
From the fit $U = aI + b$ we get $R = a \pm u_a$.

\section{Discussion and conclusions}
Agreement with Ohm's law~\eqref{eq:ohm}.
