Chapter 22, Problem 3A
What is the difference between a conductor and an insulator?
Expert Solution & Answer
To determine
To Write:Difference between a conductor and an insulator.
Explanation of Solution
Introduction:
A conductor’s main property is its free electrons which can transfer energy from one region to another. An insulator cannot transfer thermal energy because it does have free electrons.
A conductor is generally shiny as compared to an insulator. Conductors are generally hard as compared to an insulator. They are sonorous in nature. The insulators are those objects which do not allow the passing of free electrons and the thermal energy. An insulator can be wood, paper, plastic, etc. A conductor can be a metal, alloy, iron, copper, etc.
Conclusion:
Hence, the conductors have free electrons and allowthe conductionof heat and electricity. An insulator does not carry the free electrons and also not allowsthe conduction of heat and electricity.

- Part A You want to get an idea of the magnitude of magnetic fields produced by overhead power lines. You estimate that a transmission wire is about 12 m above the ground. The local power company tells you that the line operates at 12 kV and provide a maximum of 60 MW to the local area. Estimate the maximum magnetic field you might experience walking under such a power line, and compare to the Earth's field.
