Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.
The electrons flow into one end of the metal bulb bottom, they then flow into the filament where they meet heavy resistance. This resistance causes the filament to heat up and produce light as the electrons try desperately to keep moving.Another AnswerIn the case of incandescent lamps, the electricity does work on the filament, causing its internal energy to increase. This is accompanied by a rise in temperature which results in a loss of energy to the surroundings by (mainly) heat transfer and (to a lesser extent) electromagnetic energy in the form of visible light.
It is the extremely thin wire inside the bulb. It is so thin that when the electricity goes through produce light, when that filament breaks the bulb is not good.
The filament in a light bulb causes the light bulb to heat up and give off life.
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
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
The filament in the bulb has a high resistance to the flow of electricity. As electricity passes through it, the filament heats up and begins to glow, giving off the visible light you see.
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
cus it does
The resistance of the filament in a light bulb is(voltage at which the bulb is designed to operate)2/(the rated power/watts of the bulb)
Yes, a light bulb is a source of light. When current is going through the filament the resistance generates enough heat that the filament glows, producing light.
the filament
The filament in a light bulb forms resistance so that heat can happen. The electricity then converts to light energy and heat energy so that the light will shine.
Most simple incandescent light bulbs are made of a thin section of tungsten through which the current flows. This section of tungsten is called a "filament". The tungsten filament has electrical resistance and so is a resistor. As a resistor it develops a voltage drop. This voltage drop multiplied by the amperage passing through it equals the wattage of the bulb. The heated tungsten gets to thousands of degrees above room temperature and becomes hot enough to produce yellow-white visible light. As a resistor, the tungsten light bulb has a positive resistance coefficient. This means that the electrical resistance goes up when the filament becomes hot. For example, a 100 watt light bulb operated at 120 volts - it does not matter if it is AC or DC for this calculation - will have a resistance of 144 ohms when hot and draw .833 ampere. When cold the filament typically has a resistance of only 10 ohms which increases as the filament heats up.

The incandescent light bulb. The tungsten filament lights due to it's resistance of the current flowing through it.
