Assignment #3 (Chap 27, 29, 30, 31) Date: 09-05-2011 Submission Date: 16-05-
A solid cube of silver (density = 10.5 g/cm^3 ) has a mass of 90.0 g. (a) what is the resistance between opposite faces of the cube? (b) Assume each silver atom contributes one conduction electron. Find the average drift speed of electrons when a potential difference of 1.00 × 10-5^ V is applied to opposite faces. The atomic number of silver is 47, and its molar mass is 107.87 g/mol.
Material with uniform resistivity ρ is formed into a wedge as shown in Figure.1. Show that the resistance between face A and face B of this wedge is
