Conductors and insulators - FN3

Conductors and Insulators

Conductors are made of materials that electricity can flow

through easily. These materials are made up of atoms whose electrons can move away freely.

Examples of conductors are:

• Copper
• Aluminum
• Platinum
• Gold
• Silver
• Water

Insulators are materials opposite of conductors. The atoms are not easily freed and are stable, preventing or blocking the flow of electricity.

Some examples of insulators are:

• Glass
• Porcelain
• Plastic
• Rubber

Remember:

- Your body is 60% water and that makes you a goood conductor electricity. 

- The rubber or plastic on an electrical cord provides an insulator for the wires. By covering the wires, the electricity cannot go through the rubber and is forced to follow the path on the aluminum or copper wires.
