Chapter 17, Problem 27R

To determine

To Choose: The correct option.

Answer to Problem 27R

Option D

Explanation of Solution

Introduction:

Metals are good conductors of electricity. To conduct the electricity in any material, there is movement of electrons.

In metals there are number of free electrons present which move in random directions. When the electric potential is applied to the metals, the electrons flow in one direction and conduct the electricity. In general, metals are good conductors of electricity and heat. So, the electrical conductivity is the property of metals when electrons are moving freely in metals.

Conclusion:

Thus, option D is correct.
