electrical resistance
resistance
It's resistance to electric current increases.
It's resistance to electric current increases.
The resistance of the wire increases as it gets longer and thinner. This is because there is more material for the current to pass through, leading to more collisions between electrons and atoms, which results in increased resistance.
When a conductor is made thinner and longer, its resistivity increases. This is because the thinner diameter and longer length result in more collisions between electrons and atoms, leading to greater opposition to the flow of current, which manifests as increased resistance.
increases
Its length, obviously. But also its electric resistance.
With a given material, the resistance is inversely proportional to its area of cross section and so the radius. That means wire becoming thinner the resistance increases not decreases as said in the question.

Since resistance is inversely-proportional to cross sectional area, the lower the cross-sectional area, the higher the resistance. So ALL types of wire exhibit this behaviour!
The_wire_resistance_increases.">The wire resistance increases.No, the resistance of the wire decreases if a thicker (larger gauge) wire is used.
The 100w wire would be thinner than the 50w wire.Ê When determining wire gauge, the higher the wire gauge number, the thinner the diameter of the wire.Ê
