Conductors and insulators..

Here are a few common examples of conductors and insulators:

• Conductors:
• silver
• copper
• gold
• aluminum
• iron
• steel
• brass
• bronze
• mercury
• graphite
• dirty water
• concrete

• Insulators:
• glass
• rubber
• oil
• asphalt
• fiberglass
• porcelain
• ceramic
• quartz
• (dry) cotton
• (dry) paper
• (dry) wood
• plastic
• air
• diamond
• pure water

How conductors and insulators work is very important in the electrical field. For one we want to know what materials we need to construct out materials from to transports our electricity. And second we need to know how to protect that flow of electricity while being transported. And how to protect ourselves while we work on electricity.

One simple formula we use is how we can calculate the resistance of a conductor so we know how big of a cross-sectional area or how long out conductors can be to carry our electrical loads.

We can do this by using the formula.
