Problem 1: Alpha. The temperature coefficient of resistivity ? of a certain Ohmic material is defined as the ratio of the fractional change in resistivity Δp/p0 to the absolute change in temperature ΔT. Given the resistivity data below for three conductors X, Y, and Z, which among the choices is the correct order according to increasing ??

Conductor	Resistivity (10^-8 ?m) at T = 20^oC	Resistivity (10^-8 ?m) at T = 50^oC
X	100	120
Y	50	100
Z	200	250

A. X<Y<Z

B. Z<Y<X

C. Y<X<Z

D. X<Z<Y

Problem 2: Across the Universe. Which of the following statements is/are Always True?

I. The I-V curve of a nonohmic material is linear.

II. The I-V curve of an ohmic material is increasing.

III. The I-V curve of an ohmic material is logarithmic

a. II only

b. I and III only

c. II and III only

d. I, II and III.
