A conductor does not transfer energy quickly and an insulator does.
An insulator transfers an electric charge and a conductor only transfers heat.
A conductor allows electricity to flow through it easily and an insulator does not.
An insulator allows electricity to flow through it easily and a conductor does not.

an iron nail.
a plastic cap.
a silver spoon.
a metal hanger.
The correct answers are:
- A conductor allows electricity to flow through it easily and an insulator does not.
- All of the following are electrical conductors except a plastic cap.
The difference between a conductor and an insulator lies in their ability to conduct electricity. A conductor allows electricity to flow through it easily, while an insulator does not. To determine the difference between them, you can consider the properties of each.
When it comes to conducting electricity, a conductor is a material that allows electric charges to pass through it. This is because conductors are made up of atoms with loosely bound electrons. As a result, these electrons are free to move throughout the material, facilitating the flow of electric current. Examples of conductors include metals like copper, aluminum, and silver.
On the other hand, an insulator is a material that does not allow electric charges to pass through it easily. Insulators have tightly bound electrons, preventing the free movement of charges. As a result, electric current cannot flow through them. Examples of insulators include rubber, plastic, glass, and wood.
To answer the first question: A conductor allows electricity to flow through it easily, while an insulator does not.
Now, let's move on to the second question regarding electrical conductors. Among the given options, all but one are examples of electrical conductors. An iron nail, a silver spoon, and a metal hanger are all materials that allow electric current to flow through them, making them electrical conductors. However, a plastic cap is an insulator—it does not allow electricity to flow through it. Therefore, the correct answer is "a plastic cap."
The difference between a conductor and an insulator is that a conductor allows electricity to flow through it easily, while an insulator does not.
As for the second question, all of the options provided are electrical conductors except for a plastic cap.
