They both have a coil of wire in them that heats up. A light bulb make light with heat as a secondary effect while a resister generates heat and would make a small amount of light if exposed to air.
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 0.833 ampere.
When cold the filament typically has a resistance of only 10 ohms which increases as the filament heats up.
CommentLight bulbs, or lamps, are not known as 'resistors'. They certainly have 'resistance', but they are not resistors. A resistor is an electrical component designed to provide a specific value of resistance into a circuit.
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
why light bulbs are fragile
Light bulbs emit light.
Yes, e27 light bulbs are standard light bulbs in America. The e27 LED bulb is an indoor flood light. Review sellers to find ENERGY STAR rated light bulbs.
Yes, you can buy light bulbs.

Toasters and lightbulbs.AnswerA resistor is an circuit component. So, while toasters and light bulbs have resistance, they are not resistors!
photo resistors, or light dependent resistors, are devices with variable resistance, that cahnges depending on how much light is hitting the device
Headlight bulbs, high and low beam, parking light bulbs, signal light bulbs, brake light bulbs, dash light bulbs, interior light bulbs, plate light bulbs, etc.
There are no gasses used in an electric bulb. What's inside is something known as energy. It is known as this because it gives off light. Neon is a gas that is used in light bulbs.
The type of metal that is used in domestic light bulbs is known as tungsten. This is the metal that is usually found in incandescent light bulbs.
around the time that people started buying light bulbs.

Light bulbs emit light.
Many companies manufacture efficient light bulbs. These include GE, Philips, Osram, and many smaller or less-known Chinese companies. Low energy light bulbs may be fluorescent or light emitting diode based. They come in different sizes.
