Materials with a resistance of 0 ohms are called superconductors. Superconductors exhibit zero electrical resistance when cooled below a critical temperature, allowing them to conduct electricity with no loss of energy.
Materials that do not allow electricity to pass through them are called insulators. These materials have high resistance to the flow of electrical current, preventing the movement of electrons. Examples of insulators include rubber, glass, and plastic.
Yes, all conductors have resistance to some degree. Resistance is a property of materials that impedes the flow of electric current. However, some materials have lower resistance (e.g., copper) while others have higher resistance (e.g., rubber).
The nature of materials affects resistance because different materials have varying numbers of free electrons, which are responsible for conducting electricity. Materials with more free electrons, like metals, have lower resistance since electrons can flow more easily through them. Conversely, insulating materials have high resistance because they have very few free electrons available for conducting electricity.
Resistance depends on the material's conductivity, temperature, and dimensions. Materials with high conductivity exhibit low resistance, while materials with lower conductivity exhibit higher resistance. Temperature can also affect resistance, with most materials experiencing an increase in resistance as temperature rises. Additionally, resistance is directly proportional to the length of the material and inversely proportional to its cross-sectional area.

Those are the materials we loosely call "conductors".
How do you call the support of a beam, if it has rotational resistance but has no resistance to transversal displacement. i.e., at the support, u'(x)=0, (EI u''(x))'=0. If it is free to translate perpendicular to the beam but not free to rotate, it is a guided fixed support
