What's resistance?
Electrical resistance is the voltage across any component divided by the current flowing through the component. A component - eg a "RESISTOR" is designed to offer resistance to the flow of electricity/electric charges. A wire, is designed to offer as little resistance as possible to the flow of electricity. Basically, for a given voltage, the lower the current the higher the resistance, whilst the higher the current the lower the resistance. There are SOME materials which apparently offer NO resistance, and they are called SUPERCONDUCTORS (have a Nobel prize if you discover one). In terms of what's going on in the material, it's sort of electrons bouncing off fixed atoms as the electrons try to move under the influence of the voltage/electric field applied to it.
