PASCO Hall Effect n-doped Semiconductor

Purpose: The Hall Effect experiment (conducted by Edwin Hall in 1879) determines the sign of the charge carriers in current flow. A current can be thought of as a negative charge moving in one direction or as a positive charge moving in the opposite direction.
