If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
#1). Thinner wire.Either replace a wire with one composed of thinner material, orstretch the existing wire slightly so that it becomes thinner.#2). Longer wire of the same thickness.
A thick wire has its cross section area more than that of the thin one .Since the resistance of a material is inversely proportional to its resistance, resistance of thick wire is less compared to.[as cross section area increases the no electrons drifted increases].this applies only to OHMICdevices.

Resistance of wire increases wen we make it thin. Because R is inversely prop. To cross section area of wire.

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 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
A thinner wire in the bulb increases resistance and causes the metal to " burn hotter" converting the electrical energy into thermal and radiant energy
Bigger guage number = smaller diameter wire. 30 guage is thinner
