resistance has important value in electrical circuit . it has vast range of values. resistance used for limited the flow of current as you wish to limited . If a wire conducts high-frequency alternating current, then the effective cross sectional area of the wire is reduced because of the skin effect.A metal consists of a lattice of atoms, each with a shell of electrons. This is also known as a positive ionic lattice Just as the resistance of a conductor depends upon temperature, the resistance of a conductor depends upon strain.
