WilsonElectrical Conductors     Even if you're never going to repair a lamp or make a chick brooder, you should know about conductors and insulators. This is because you happen to be a fairly good conductor of electricity. Electricity will pass easily through you to other conductors—the ground, for instance.When this happens you may get a shock, burn, or serious injury.But it doesn't ever have to happen, if you learn to understand your friend, electricity.     Silver, copper, iron, aluminum and many other metals are very good conductors. Water, acids, and salts are too.Electricity passes over or through them very easily.Like water pipes, the larger the conductor, the more electricity it can carry. When conductors are too small for the amount of electrons trying to move over them, they get hot, melt, or may start fires. That's why wire size is important.Electrical Insulators     Insulators are the opposite of conductors. Electricity has trouble passing through some materials. Rubber, most plastics, dry wood, oils, and glass are some of the good insulators. It's the amount and kind of insulation that counts.If it has enough force, electricity can pass through just about anything—even jump gaps!     Electricity, like water, flows along the easiest paths. It is always trying to get to the ground. The earth attracts it. It stays on the wires unless a person, a wet branch, or some other conductor gives it a path to the ground.Do not touch any wire which might be carrying electricity.
