Q1: Resistivity of hard drawn copper is

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. Hard drawn wire is most commonly used in shelving, automobile parts, and shopping carts.

Annealing is the metallurgical term for heating a material (generally a metal) and subsequently cooling it to change its properties (such as its hardness or durability). Annealing copper makes it softer and less brittle, which allows you to bend it without breaking it.
