Answer:
Conductors allow electricity to pass through them, while insulators do not allow electricity to pass through them. Two examples of conductors are iron and steel. Two examples of insulators are plastic and glass.
Explanation:
When you put conductors in a circuit, it would result in a closed circuit while when you put insulators in a circuit, it would result in an open circuit. This is mainly because electricity can pass through conductors but not insulators. Metals are mostly conductors of electricity while non-metals are mostly not.
