Want this question answered?
Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
Electrons
When the two ends of the conductor are connected to a source of EMF, electricity flows through it.
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.

Incandescence. The filament is heated by the electricity moving through it, this causes the filament to heat up, and the heat causes the familiar glow.
Heat, which then produces light.
the simple answer is resistance, the filament is a very fine wire (usually tungsten) that heats up and glows when power is applied

No. The filament completes the circuit, so if the filament is blown the circuit is incomplete, so no electricity flows.

Simply put, no. A light bulb lights up because the filament inside (the thin wire that often breaks) has a lot of resistance in it, then when electricity flows through it, it heats up and glows brightly.
Some is changed into light and heat energy and some continues through the curcuit
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
Electricity flows in a complete circuit
When a flash light is switched on the circuit between the lamp and the batteries is complete. When the circuit is complete, the electrons flow from the positive terminal of the batteries through the tungsten filament back to the negative terminal of the batteries. Once the electricity flows through the filament it starts glowing producing a bright light. When the the torch light is switched off the circuit is broken and the flow of electricity is disrupted switching off the light.
