The heat and light of the filament in an incandescent bulb is simply the power
dissipated by the resistance of the filament. The power dissipated by a resistor
is simply (current through it)2 times (its resistance). A thicker wire used as the
filament has less resistance, which means that for any given current through
it, it dissipates less power than a thinner filament would.
In simplest terms, the thicker the filament is, the more juice you must jam
through it to make it glow.

Increasing the thickness of a tungsten wire will increase its cross-sectional area which will reduce its resistance. The filament of a higher-wattage lamp has a lowerresistance than the filament of a lower-wattage lamp, This is so because the power of a lamp filament is determined by dividing the square of the voltage by its resistance -the lower the resistance, the higher the power output. So reducing the resistance (by increasing its thickness) of the tungsten filament will increase its power output and, therefore, increase its brightness.
A thick tungsten wire like any other conductor will allow electricity to pass through with little or no resistance to the electrical flow. What happens next depends on the rest of the building circuit completed by the tungsten wire. Most likely, a fuse or circuit breaker will be triggered to prevent overheating of the wiring. if that doesn't happen, either the tungsten wire will overheat an melt, breaking the circuit or the building wiring will heat up and melt or something around the wiring will get hot enough to burst into flame.
The tungsten wire in a light bulb is a resistance wire. It is the current flow through the wire that causes it to glow. The larger the diameter of a wire the less the resistance becomes in that wire. Assuming the lengths of the filaments are identical, the results of the lower resistance in the bulb, the lamp would become brighter when a current was passed through it.
A lot less would happen if there were no light bulbs because everyone would spend the time creeping around in the dark.

Electric bulb is basically an insulating device. By calling it an insulating device it does not mean that it completely disallows the flow of electricity! It means that the device or object resists the flow of electricity to some extent. It has a coil of a metal called Tungsten which resists the flow of electricity. Due to this resistance the coil heats up immensely and glows hot. However, this coil of Tungsten does allow some electricity to pass through so that the circuit of electrical flow remains closed/complete and the electric bulb remains lighted.
Its a coiled tungsten filament.

Glass, inert gas, tungsten, other metals.
Examples are the tungsten element inside a light bulb, and the heating element bars of an electric fire.

It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!
Halogen gas is in a Tungsten-Halogen Light Bulb.
A filament bulb resistor is the common type of light bulb. It contain a thin coil wire called filament. It produces light as a result. It is made mainly from the element tungsten. The metle tungsten has very high melting point and it is a good conductor of electric current
