Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Tungsten is commonly used as a filament in light bulbs due to its high melting point and resistance to heat. It can be shaped into a thin wire that glows when an electric current passes through it, producing light.
The bulb that glows brightly likely has a higher current passing through it compared to the dim bulb. This could be due to differences in resistance, voltage, or power ratings of the two bulbs.
The filament that glows white hot in electric light bulbs is typically made of tungsten. Tungsten has a high melting point and is able to withstand the high temperatures produced when an electric current passes through it, creating the desired white light.
Incandescent light bulbs use tungsten( a metal which can withstand very high temperatures) as filament.When heated to a very high temperature, the filament glows emitting light and heat. Heating effect in filaments is caused by the property of resistance in conductors. On reducing the cross- section area( thickness) of the filament, its resistance is increased and hence the filament glows with comparitively lesser electric current.
In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

Both glow. but male fireflies would glow brighter as they have 2 'bulbs' while female fireflies only have 1

Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.
it glows and emits light.
You use a light bulb.Such light bulbs use different types of technology; for example, the old-fashioned (and quite inefficient) incandescent bulb heats a wire, which acts as an electrical resistance, to the point where it glows.
With the moon. The sun is actually bouncing light off of the moon to get to the earth, that's why the moon tends to look like it "glows". So with that light, the night would be brighter with the moon
If one more light bulb is added to a series string of light bulbs while the voltage supplied across theends of the string remains constant, then the total resistance of the string increases, causing thecurrent in the string to decrease, and every bulb glows less brightly than it did before the new onewas added.

A 100W bulb will generally glow brighter than a 75W bulb because it consumes more power and emits more light. The higher wattage means that more energy is being converted into light, leading to a brighter glow.
