A conductor and a switch
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.
Corona wires are thin wires that carry electricity and are used in photocopiers and printers to create a static electrical field. This field helps transfer the toner from the cartridge onto the paper by attracting the toner particles. The corona wires are negatively charged to attract the positively charged toner particles for printing.
Magnetism is a force not a substance. As such it can not be applied to paper.
It is called Cuticle and composed of cutin, a wax like material which is chemically a hydroxy fatty acid
the seed coat
No, polythene is a plastic and that cannot conduct electricity.
In low voltage wires, the insulation factor of the coating determines the wire's voltage rating. A wire coating of cross linked poly vinyl is used as an insulation. High voltage transmission wires uses no coating on the wire
Yes this is because electricity cant run through it very well
A coat hanger is a horrible conductor of electric current. Doubt if it would work. Also most distributor wires are hot. Since coat hangers aren't coated it could easily ground out.
A metal coat hanger is a conductor of electricity because it is made of metal, which allows electric current to flow through it easily. Insulators, on the other hand, do not allow electric current to flow through them easily.
a coat is an insulator because it keeps heat in
Coat wires typically consist of a conductive material such as copper or aluminum surrounded by an insulating material like PVC or rubber. Poor conductors, on the other hand, are materials that do not allow the flow of electrical current as easily as conductors, such as rubber, wood, glass, or plastic.
A jacket can be used as an example of a conductor.

it's an insulator. conductors are things like metals or salts.
Varnish is not a good conductor of electricity because it is an insulating material. Insulators like varnish have high resistance to the flow of electrical current due to their molecular structure, which does not allow free movement of electrons. In fact, varnish is often used to coat electrical wires and components to prevent electrical conduction and protect against short circuits.
