Conductors/Insulators

Hello dear Scientists!
              
 In addition to Coulomb’s static electricity, we have discovered conductors and insulators. Conductors allow electric current to flow through easily while insulators make it so that they cannot flow as freely. Insulators tend to have a great resistance, while conductors do not. This is why when you have a circuit; metal wires are used because they have good conductivity. However, people cover them in an insulator (such as rubber or plastic) as a safety precaution—just so that they will not get electrocuted!
              
For conductors, the charged ions tend to distribute itself evenly, but in insulators it can’t. Think about this: If you’re fishing and you have a bunch of holes in your net, the fish swim through really easily. However, if your net has very small or a little amount of holes in it, the fish can’t swim through all that well, and you collect more fish that way!
                

Metals and water tend to be really good conductors. Even the human body serves as a good conductor. That means you need to watch out for electricity so that you don’t hurt yourself! Insulators are usually Styrofoam, paper, rubber, glass, and dry air.  In winter, your hair gets more static-like in winter. It has charge build-ups, so that the charge in your hair is a lot more than usual and creates this imbalance. This is another reason why our hair is so wonderfully crazy in Winter!
                
I hope this helps you and your future endeavors to understand the world around you!
