What is the fluid in a fluorescent light bulb?

In a fluorescent light bulb there is usually a drop of mercury. That mercury vaporizes as the bulb warms up and it becomes gaseous, enhancing the electron interaction through the bulb, making it brighter.

Can higher voltage burn the fluorescent bulbs?

it all depends on the voltage the light bulb can sustain.

In 1879 this invention Thomas Edison burned for 13 hours?

The light bulb. The light bulb. The light bulb.

What is the Function of light bulb in an electric circuit?

The function of a light bulb in an electric circuit is that it turns electrical energy into light.

Which is more efficient loaded or unloaded circuits?

Efficiency is typically associated with minimizing losses in a circuit. If you have no load you couldn't compute efficiency. If there is a load you need to determine what you are trying to measure. For example, in an incandescent light bulb a lot of power is wasted in heat. So if light is what you are looking for an incandescent bulb isn't very efficient. A compact fluorescent would be more efficient. However, if you were using a light bulb to power an "Easy Bake" oven it would be more efficient.

How a fluorescent light bulb works?

Fluorescent light bulbs have a gas inside of them called Mercury. The way that the light bulb works is that it uses electricity to "excite" the mercury atoms. This causes the mercury atoms to give of short wave ultraviolet light. this causes a phosphor which is any substance that can illuminate to fluoresce or emit light.

How many atoms of mercury are in a light bulb?

Compact fluorescent light bulbs contain mercury. (For that reason, it is important to be very careful with a broken compact fluorescent bulb, because mercury is highly toxic.) Most other kinds of light bulbs do not contain any significant amount of mercury.

What is the fluid in a fluorescent light bulb?

In a fluorescent light bulb there is usually a drop of mercury. That mercury vaporizes as the bulb warms up and it becomes gaseous, enhancing the electron interaction through the bulb, making it brighter.

How does a compact fluorescent bulb convert electricity into light?

A compact fluorescent bulb uses electricity to create an electrical current that passes through a tube containing argon and a small amount of mercury vapor. This current excites the mercury atoms, causing them to emit ultraviolet light. The UV light then hits the phosphor coating inside the bulb, which converts it into visible light.

What energy transformations occur in a compact fluorescent light bulb?

In a compact fluorescent light bulb, electrical energy is transformed into light energy through the excitation of mercury vapor atoms inside the bulb. Some electrical energy is also transformed into heat energy due to resistance in the bulb's circuitry and the phosphor coating on the bulb.

The light-producing element in a fluorescent bulb is the?

The light-producing element in a fluorescent bulb is mercury vapor. When electricity passes through the gas, it emits ultraviolet light that then excites the phosphor coating inside the bulb, causing it to emit visible light.

Is fluorescent light produced by heat?

Fluorescent light is not produced by heat. It is produced when electricity passes through the mercury vapor in the fluorescent tube, causing the mercury atoms to emit ultraviolet light that then interacts with the phosphor coating inside the tube to produce visible light.

Why does a fluorscent light not work in the cold?

fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.

Which state of matter forms when a fluorescent light bulb is turned on?

A fluorescent light bulb produces light by exciting the gas inside it, usually mercury vapor or neon. The excited gas atoms emit ultraviolet light, which stimulates a phosphor coating on the inside of the bulb to produce visible light. So, when a fluorescent light bulb is turned on, it emits light through a process involving excited gas and phosphor.

Why is mercury in fluorescent bulbs?

Mercury is used in fluorescent bulbs as it helps produce ultraviolet light when electricity passes through the bulb. This UV light excites phosphor coating inside the bulb, which then emits visible light. While the amount of mercury used in fluorescent bulbs is small, it is essential for their function and energy efficiency.

Is there mercury in flouresent light bulb ballasts?

Yes, some fluorescent light bulb ballasts contain mercury as part of their design. Mercury is used in fluorescent bulbs to help create ultraviolet light, which then interacts with the phosphor coating inside the bulb to produce visible light. However, newer ballasts may use alternative technologies that are mercury-free.

Did peter cooper hewitt invent the fluorescent light bulb?

Yes, Peter Cooper Hewitt did invent the first mercury vapor lamp, which was a precursor to the modern fluorescent light bulb. The technology evolved over time to what we now commonly refer to as the fluorescent light bulb.
