Question 1 Report
Which of the following is not a conductor of electricity?
Answer Details
Glass is not a conductor of electricity. This is because it is a non-metallic material and does not have any free electrons to carry the electric charge. In contrast, metals such as silver and copper are good conductors of electricity because they have a large number of free electrons that can move easily through the material in response to an electric field. The human body can also conduct electricity to some extent, although this can be dangerous depending on the circumstances. The Earth is a complex case - it is a good conductor of electricity in some contexts, such as during a lightning strike, but is not a good conductor in other contexts.
