Q1: Resistivity of hard drawn copper isA less than that of annealed copper
B more than that of annealed copper
C same as that of annealed copper
D decreasing when temperature increases
ANS:B - more than that of annealed copper Hard-drawn wire is the most basic and affordable steel wire available. The term "hard-drawn" simple means the steel has been drawn through the die to the desired diameter with no additional processing or tempering.
