Learning Goal: Examine the dependence of resistivity and resistance of a wire on temperature and how it affects the potential difference across the terminals of the wire. Introduction: A current of 65 milli-amperes (mA) flows through a wire of length L= 1.7 meters long and diameter of d= 1.15 millimeters at a temperature of T0= 20 °C; the wire's resistivity at this temperature is ρ0= 5.33×10−8 Ω ∙ m. The temperature coefficient of resistivity of the material is α= 4.6×10−3/C°....

Question 2 (a) Explain what is meant by the effectiveness of a strut or beam. b) Give an example of each of these scaling effects: (i) fundamental scaling (ii) atomic effects on scaling. (c) An example of a quasi-fundamental scaling effect is that the natural frequency fo of a beam changes according to its dimensions only - E and p are independent of scale. If the scale of a beam is denoted by L, and given that: nc vent no...

1. The energy bands at the top of the valence bands in Si are three-fold degenerate (neglecting spin). The secular determinant for states near k 0 can be obtained by perturbation theory and is Ck,kz Ckxkz y z where E is the energy of the state k (kx, ky, kz), and A, B, and C are components of the reciprocal mass tensor. Find an expression for the energy bands near...
