Which of the following objects is not a conductor of electricity?
Answer Details
The object that is not a conductor of electricity is "Dry wood."
A conductor of electricity is a material that allows electrical current to flow through it easily. Materials like metals, such as iron, are good conductors because they have a lot of free electrons that can carry electric charge.
However, dry wood is not a good conductor of electricity. This is because wood is an insulator and does not have free electrons that can carry electrical charge.
In summary, the Earth, human body, and iron rod are all conductors of electricity, but dry wood is not.
