For a certain resistor with a normal (that is, room temperature) resistance of 150 Ω, the values of the constants in Equation (11.4) are found to be A = 4.05, B = 4.22, and K = 4.11, in units such that R will be in ohms and T in kelvin. What is the resistance of this resistor at (a) T = 77 K, (b) T = 20 K, and (c) T = 1 K?
