hat is the specific goal of this lab ? Exactly what question (s) are you trying to [swer ? Be as specic as possible . ("To learn about topic X...' is not specific!) 'hat specific measurements or observations will you make in order to answer this lestion ? he following set of questions will help you determine the sign of the charge car- ers from the sign of the Hall Voltage. Shown below are two possible cases: one ith the positive charge carriers, and one with negative charge carriers. A few charge irriers are shown in each figure. In both figures, the conventional current flows to 1e left , and the magnetic field points along the thickness direction (into the page ). a) On each figure, draw the velocity vectors for the charges. Remember that con- vention alcurrent is defined as the ow of positive charge
