Extracted text: Solved problems 1. A current of (0.12 A) pass through n-type semiconductor have a width of (w = 2 mm) and thickness of (d = 1 mm). If the voltage along the width of this sample of semiconductor is (3.4 mV) and a normal magnetic field of (500 Gauss) applied on this piece of semiconductor, find the Hall coefficient and electron density?
