What will happen if you use Nichrome instead of tungsten in an electric bulb?

Answer: Melting point of the metal is lower than what the wire would heat up to in an evacuated globe. So,Tungsten, is used instead where the filament can reach 3200C. When the temperature is under 1000C, then Nichrome (An Alloy of Chromium and Nickel) is used as a resistance heating wire.

Why Nichrome wire is not used in electric bulb?

Nichrome wire, an alloy of nickel and chromium, and often iron (or other elements) is good for making heaters but not lamps. At rated voltages, nichrome will glow orange-red, not the bright white that is needed for illumination. If you increase the voltage to get a brighter color, the nichrome will burn open (melt.)

Is tungsten a better conductor than Nichrome?

Answer: Tungsten is the better conductor than Nichrome.

Why do we use only tungsten in bulb?

Incandescent bulbs typically use a tungsten filament because of tungsten’s high melting point. A tungsten filament inside a light bulb can reach temperatures as high as 4,500 degrees Fahrenheit. A glass enclosure, the glass “bulb”, prevents oxygen in the air from reaching the hot filament.

What is the difference between Nichrome and tungsten?

Tungsten is made of tungsten while Nichrome is made of nickel chromium. Tungsten is used to make filament of bulbs. Nichrome have high resistivity than tungsten.

Why is Nichrome used in electric heater?

Note: A nichrome wire is used as a heating element because of its high melting point and high resistivity (low conductivity) also. Having a high melting does not allow the nichrome wire to melt easily when a large amount of heat is produced.

What is the difference between nichrome and tungsten?

Can we use tungsten instead of nichrome in electric heating appliances?

Pure tungsten has some amazing properties including the highest melting point (3695 K), lowest vapor pressure, and greatest tensile strength out of all the metals. An electric current can heat the filament around 2000-3300 K, which stays below the melting point of tungsten but above that of nichrome.

What is the best substitute for tungsten?

Other metals (osmium, tantalum, molybdenum) have been used as well, but tungsten seems to outperform them, at least once production cost is considered as well.

Why is tungsten used in bulbs not in fuse wire?

Tungsten is a metal whose melting point is very high. It is used in bulbs because tungsten will not catch fire in the bulb. But it is not used in fuse wires because fuse wires need a low melting point. Fuse wire need to have low melting point ,when excess current flows,the wire melts and circuit is broken.

What can be used instead of Nichrome wire?

Nichrome is good, steel or stainless steel should also work ok and may be preferred if you need less heat and more strength.
