Question

How can tungsten wire make high temperature using its high resistivity?

Answer 1

Answer:

Tungsten is a good conductor. Resistivity oftungsten is only about twice that of aluminum, and tungsten has lower resistance than iron, steel, platinum, lead. Note that the filament lead-in wires are typically iron, which hasnearly twice the resistivity of tungsten

Answer 2

Answer:

Tungsten is a good conductor. Resistivity of tungsten is only about twice that of aluminum, and tungsten has lower resistance than iron, steel, platinum, lead. Note that the filament lead-in wires are typically iron, which has nearly twice the resistivity of tungsten. Why doesn't the iron light up, and the tungsten remain dark?

Light bulb filaments aren't resistive because of the tungsten. They're resistive because of their very long length, and very thin wire. The filament in a clear bulb appears spiralled, right? It's clearly much longer than it looks, and much thinner. But in many bulbs, the spiral itself is composed of even smaller spirals. (Some large high-wattage bulbs even have yet a third level of smaller spirals.) A 2cm filament may actually be many tens of cm of extremely thin wire, as below:

We use tungsten not because it's especially resistive, but because it's "refractory," and most other inexpensive metals would melt long before they heat up to "white" temperatures above 2500Kdeg. Early lightbulbs used filaments of platinum, iridium, rhodium, etc., but Edison's bamboo-carbon filaments made bulbs affordable.
