If a wire is bent to form loops, it acts as an inductor. Each loop of the inductor exhibits a capacitance effect with the next loop. That is, a bent wire will exhibit all three properties: inductance, resistance and capacitance. So, explicitly, the resistance of the wire doesn’t change when you bend it.

In the electrical field, the purpose of any insulating material is to separate electrical conductors without passing current through it. Material like PVC, glass, asbestos, rigid laminate, varnish, resin, paper, Teflon, and rubber are very good electrical insulators.

Whta happend when you bent the wire in different directions​ Because the magnetic field created by the electric current in the wire is changing directions around the wire, it will repel both poles of the magnet by bending away from the wire.

If you bend the material too much it will undergo inelastic deformation and can become more brittle due to dislocation formation, and eventually form cracks and fracture.

Rubber slippers When bent, rubber slippers change in size and shape but no new material is formed.

Today I found out that the paperclip was used as a symbol of resistance during World War II. In April of 1940, just a few months into World War II, Adolf Hitler knew that he needed a way to break past the Allied blockade of Germany if he had a hope of winning the war.

Check out 14 handy alternative uses for the humble paper clip.

Cut out a small rectangle shape from the paper and attach a paperclip to each end. This is because the metal paperclips do conduct electricity but the paper does not. Metals are good conductors of electricity , so wires are made from copper, which has the added advantage that it can be stretched thin without breaking.

Is a penny a insulator? Yes, pennies are pretty good conductors. As Joseph Lee mentioned, US pennies are made from copper, which is one of the best electrical conductors. … Steel is also a very good electrical conductor, albeit not in the same league as copper.

Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Electrical wires are made of metal because metal is one of the best conductors. Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity. This is why electrical wires are covered in rubber, plastic, or cloth.
