FAQ

Those who are looking for an answer to the question «Why is the filament of an electric bulb thinner?» often ask the following questions:

👉 Electric bulb filament?

The filament of an electric bulb is not purely resistive. It contains a very high impedance. By impedance, we know, Z = R + j(X L – X C) As a result, this filament doesn’t only have a resistive quality but also has inductive and capacitive quality. Among these, the resistive quality is very negligible. Resistive nature of filament varies with the variation of power rating of bulb. But it is very less compared to the reactive quality of the electric bulb.

👉 Electric bulb filament is made up of?

▶️The filament of electric bulb is made up of Tungsten wire because the wire has low melting point and has high tensile strength out of all other metals.

👉 Filament in an electric bulb made of what?

Electric bulb filament is made up of? Tungsten. Filaments in incandescent light bulbs are made of tungsten. Whenever an electric current goes through the filament, the filament glows. It may also be known as the electron emitting element in a vacuum tube.

14, why use a long Incandescent Bulb is usually smaller than the same specifications of the new Incandescent Bulb? This is because the filament sublimation and thinning, so that the lamp resistance becomes larger, through the filament current becomes smaller, when the voltage does not change, the actual power becomes smaller.

Light output of similar 230 V bulbs is slightly less. The lower current (higher voltage) filament is thinner and has to be operated at a slightly lower temperature for the same life expectancy, which reduces energy efficiency. The lumen values for "soft white" bulbs will generally be slightly lower than for clear bulbs at the same power.

Heating platinum in a better vacuum degassed the filaments and in turn enabled them to be thinner and to withstand higher temperatures. It would also make the system cheaper since individual circuit breakers were no longer needed for each lamp.

Vinay Kumar, Meritnation Expert added an answer, on 10/9/13 As the electricity is passed through the filament it gets heated because of it's resistance and when it's heated to suitably high temperature range it'll emit light. The intensity of light emitted will be proportional to the surface area of the filament.

For a fixed voltage (ie. in a domestic light bulb) the thicker the filament the lower it's resistance and so less energy is converted into heat - the filament is dimmer. Brighter filaments are thinner, have higher resistance and so heat up more -> brighter. This is also why low wattage bulbs in cellars and cupboards last so long.

Over the early years of incandescence bulbs technology, the result was achieved by merely sucking out the air from the bulb-inside so turning it into a vacuum, yet the big problem stemming from this approach was that the white-hot filament facing the vacuum underwent sublimation at an appreciable rate, that is solid Tungsten of the filament turned slowly into vapor causing the filament to make thinner and thinner until it broke and the bulb die; moreover, the metal vapor condensed on the ...

As an incandescent bulb is used, it is slowly getting thinner and thinner. It is literally evaporating atoms due to the high heat. (This is one of the reasons that a coil shape is used. It allows some of the boiled-off atoms to re-deposit.) As the filament gets thinner, its electrical resistance increases, which increases how hot/bright it is.

Resistors and Conductors The tungsten filament is what is called a resistor–an electric component designed to resist the flow of electricity. That is one of the reasons why it is so thin. The thinner a wire, the harder it is for electricity to pass through and the more resistance the wire poses.

Dual Filament Light Bulb for Corner Lights. To determine which contact is which, hold the bulb sideways in front of you, glass bulb to left and contact end to right. Rotate it until you see the two pins on sides of the base. One pin is close to the base end, the other pin is farther up the base closer to the glass.

It was Humphry Davy, an English scientist who developed the first light bulb in 1800. What is a light bulb? A light bulb is an electric light made up of glass inbuilt with a filament. The inside of the bulb was filled with some inert gas for protection of the filament by oxidation. When the filament got the electric current, it was heated up, and this heat gives the light to the bulb. Pre-commercial developments Early developments of incandescent light bulb

Why electric bulb fuse?

First of all, you have to understand why wires are used in an electric bulb filament and also in a fuse. In case of a bulb, it is expected that the filament will heat up to a very high level as to radiate visible bright light. So the element of the filament has to be of high melting point, such as Tungsten.

Why are electric guitar strings thinner?

Another reason your electric strings might feel looser than an acoustic is the nature of the strings themselves. An electric guitar’s strings are usually thinner than acoustic strings, making them much easier to press down on.
