Question

Which of the following are the characteristics of alloys with respect to the pure metal?


A
High melting point and low conductivity
loader
B
High melting point and high conductivity
loader
C
Low melting point and low conductivity
loader
D
Low melting point and high conductivity
loader

Solution

The correct option is D Low melting point and low conductivity
An alloy is a mixture of two or more metals or a metal and a non-metal. The electrical conductivity and melting point of an alloy is generally lesser than that of pure metals.

For example, brass is an alloy of copper and zinc (Cu and Zn) and bronze, an alloy of copper and tin (Cu and Sn) are not good conductors of electricity.
Copper is widely used for making electrical circuits as it is an excellent conductor.
