+\section{Suppose a DC motor is connected to a load - how would you detect a stalled-rotor condition?}
+Assume the header in Listing \ref{code:motor-stall-header} is provided. Discuss the implementation of stalled-rotor detection in the following circumstances:
+\begin{itemize}
+        \item The DC motor features only a current sensor.
+        \item The DC motor features only an encoder.
+\end{itemize}
