Insulators and Conductors
Quite the electrifying subject!
What are insulators?
Insulators are items that do not allow energy to flow through them. These items often don't have metal in them.
List of Insulators
Insulators include items such as string, wool, wood, glass, plastic, rubber, etc. This is why a car is regarded as a safe place during a thunderstorm, because of the rubber on the tires.
What are Conductors?
Conductors are materials that allow energy to flow through them well.
They usually have metal or some form of material that can be heated.
Conductors include pennies, nails, wires, etc.
How are they used in circuits?
Insulators
Insulators are used in wiring to protect people from getting shocked. The material surrounding a copper wire allow you to hold the wire without a risk of being electrified.
Conductors
Conductors are used to move electricity, energy, and electrons around a common household. It works simultaneously with insulators, which creates wires that are safe.
