Light Bulbs and Artificial Lighting

Thomas Edison and Nikola Tesla were the two inventors who made significant contributions to proving the practicality and usefulness of the light bulb and electricity. Edison is credited with developing the first commercially viable electric light bulb, while Tesla made advancements in alternating current (AC) electricity transmission.

Thomas Edison invented the light bulb to provide a practical and efficient way to produce light without the use of gas or open flames. He improved upon previous designs to create a longer-lasting and commercially viable electric lighting system.

It is called metal,plastic or steel so copper is also magnetic which alows the copper to make the bulb be brighter and to light up thankk you for listening...

Fluorescent colors are extremely bright and vibrant colors that appear to emit light when exposed to ultraviolet (UV) light. They are often used for high-visibility applications such as safety signs, posters, and outdoor advertising. These colors can be found in various mediums like paints, markers, and dyes.

Tungsten has a higher melting point and is more chemically stable than copper, making it better suited for the high temperatures and chemical environment inside a light bulb. Tungsten also has a higher resistance to heat, which allows it to maintain its structure and emit light efficiently over a longer period compared to copper.

It depends on the type of bulb. Incandescent bulbs convert about 90% of the energy into heat and and only 10% is put off as light. LEDs, for instance, are much more efficient, converting almost 90% of the input energy to light. So, a 5 watt LED will convert about 4.5 watts to light, while a 25 watt incandescent will only convert 2.5 watts into light.

When your circuit is in SERIES, each individual bulb will receive one fraction of the voltage of the battery, allowing the full chain of bulbs to draw less current, but to be dimmer in the same respect.

When your circuit is in PARALLEL, each bulb will receive the same voltage, however more current will be drawn, so it depends on your situation on which you should use.

Adding one more battery to a parallel circuit of two light bulbs would increase the voltage across the entire circuit. This would cause both light bulbs to shine more brightly as they receive more power. It will not affect the current flowing through the circuit but will boost the overall energy provided to the circuit.

Licking a light bulb can result in an electric shock and a burning sensation on the tongue. It is not safe to lick a light bulb as it can lead to injury or harm.

No, a light bulb is not an electromagnet. A light bulb contains a filament that produces light when current flows through it, whereas an electromagnet is a device that produces a magnetic field when current flows through a coil of wire.

Fluorescent tubes typically produce white light when they are functioning properly. However, a red glow may occur if the phosphor coating inside the tube is damaged or if the tube is nearing the end of its lifespan. This can cause the phosphor to emit a reddish light instead of the normal white light.

Preheating in a fluorescent light helps to initiate the ionization process in the lamp's phosphor coating, which is necessary for the lamp to emit light efficiently. By preheating the electrodes, the lamp is able to start up quickly and reach full brightness faster than if the electrodes were not preheated.

It is called a socket or base. This keeps the bulb securely in place and allows electricity to flow directly to the bulb.

When a particle passes through a light bulb, it interacts with the atoms in the filament of the bulb. This interaction can cause the particle to lose energy, which results in the emission of light. The emitted light is what we perceive as the light produced by the light bulb.

It is time for bed

well that a stupid answer! here's an answer a surge of electricity goes on the wire and then boom light!

The incandescent light bulb does not contain plasma. It operates by sending electricity through a tungsten filament, which heats up and produces light. Plasma is found in fluorescent and neon light bulbs, where gas is used to create the light.

The long thin light bulb is called a fluorescent tube or a fluorescent light bulb. It is commonly used in commercial buildings, offices, and schools for general lighting purposes.

Yes, light bulbs themselves are considered nonluminous because they do not produce light on their own. They require electricity to pass through a filament, which then emits light, making the bulb appear luminous.

Fluorescent light bulbs can not be connected to a constant voltage power supply, or they will self destruct. They must use a ballast in order for this not happening. This way they can operate under 430 mA, with a drop of 100 volts. The larger the bulb, the more voltage needed (going all the way up to 1.5 A).

To remove a U-shaped light bulb, first make sure the power is turned off. Then, carefully twist the bulb counterclockwise to loosen it from its socket. Gently pull the bulb straight out once it is free from the socket.

A 100 watt bulb is brighter than a 25 watt bulb because it consumes more electrical power, which in turn generates more light output. The higher wattage allows the bulb to emit more brightness and illuminate a larger area.

Well because it is transparent and is the worst coductor of heat .Glass also does not conduct electicity. thereforeplastic cannot be used forlightbulbs because it will burn and no other material is trasparent or see through. So glass is the best material to use for lightbulbs.

Tungsten is used as the filament in incandescent light bulbs because of its high melting point and ability to emit bright light when heated.

For Light bulbs:
The filament is made of tungsten. There is a inert gas used around the filament which is usually argon, neon, or nitrogen.
