Insulators are very poor conductors of heat and electricity. Coating wires with insulators help reduce electrical disturbance between two conducting wires arranged closely. Insulators also greatly reduce of someone getting shocked if the conducting wires are left as it is.
In the application of electrical wiring:the conductor (e.g. copper) carries the electricity where it is neededthe insulator (e.g. PVC) around the conductor keeps the electricity from going where it is not neededThere are many many other applications, this is just one.
Paper is a resistor, but it is a bad idea to use them in electrical equipment at all.

Metal is not a good insulator of electricity because its electrons are free to move around, making it a good conductor of electricity instead. When a voltage is applied to a metal, these free electrons can easily flow through the material, creating an electric current. This ability to conduct electricity makes metals unsuitable for use as insulators in electrical applications.
Paper is made of wood, and wood is a conductor, partly. Wood conducts heat very slowly, but not electricity or other types of energy. If you were to link an electrical circuit with a bit of paper, the circuit would not be complete. If you were to wrap a sheet of paper around a cup of tea to keep it warm, it wouldn't work as effectively as another material.
Depends on the material, not the item. Metals are conductors, so a metal screwdriver blade Will be a conductor.
Wood is not a conductor for electricity. IT is actually a good insulator.
"Electrical circuit". "Electrical" meaning "electricity". "Circuit" meaning "around from the start back to the starting place". If any of the materials in that circuit path are not conductors, there is no circuit. The electricity only goes that far and stops. So all materials in the circuit must be able to conduct electricity.
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.
Electricity energy is carried around a circuit by the flow of electric charge, typically carried by electrons within a conductor such as a wire. When a voltage is applied, electrons are pushed through the circuit, creating a current that carries the energy from the power source to the load.
insulator
Rubber, unless soaking wet, is an insulator (will not conduct electricity).
