GEOLOGY

Detailed explanation-1: -Materials that allow electric current to pass through them easily are known as good conductors of electricity. Eg: Iron, Copper, Silver, etc.

Detailed explanation-2: -Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators. You will notice this if you have ever plugged something into a wall outlet.

Detailed explanation-3: -Conductors are the materials or substances which allow electricity to flow through them. They conduct electricity because they allow electrons to flow easily inside them from atom to atom. Also, conductors allow the transmission of heat or light from one source to another.

Detailed explanation-4: -Metals such as copper, silver and gold are good conductors because they have a lot of free electrons. When enough potential difference is applied, any medium will start to conduct electricity.

Detailed explanation-5: -Lead is a good conductor of electricity.
