What is the difference between a conductor and an insulator?

• An insulator allows electricity to flow through it easily and a conductor does not

• A conductor will not allows electricity to flow through it easily and an insulator does not.

• A conductor allows electricity to flow through it easily and an insulator does not.

• A conductor is magnetic and an insulator is not

• The longer one

• The shorter one

• There is no positive side

• They are both positive, I'm positive of it.
