A Hаll effect experiment is perfоrmed оn а semicоnductor with а length of 2.65 cm and width=height=1.70 cm, in a magnetic field of 0.5 T. The current in the sample along its length is 200 µA. The potential difference along the length of the sample is 195 mV and across the width is 21.4 mV. The charge carriers are positive so that the contribution of electrons is ignored. Sketch the experiment ensuring that you note the directions of currents and fields correctly. What is the concentration of the positive charge carriers? If the sample has a resistivity of 10
