Why do the light bulb remain unlit when the electrodes were placed in the deionized water?
Best way to explain this Question is by giving a counter example;
Light bulb will light up when electrodes are placed in an ion solution. Why is that?
This is because when a potential difference is created in an ion solution, the ions are able to react in a redox (reduction and oxidation) reaction. This allows the path of the electrons to be continued even in the liquid medium; This is why we see the light bulb light up!
Now to answer the original question, the light bulb cannot light up in deionized water because there exists no ions within the solution. This means that the circuit no longer exists at the liquid medium thus the light bulb will remain unlit

What are the six main components of a fluorescent tube light?
The six main components of a fluorescent tube light are the glass tube, which contains the gas and phosphor coating; the electrodes, located at each end, that emit electrons; the mercury vapor, which ionizes to produce ultraviolet light; the phosphor coating, which converts UV light into visible light; the ballast, which regulates the current flowing to the lamp; and the end caps, which connect the tube to the electrical circuit. Together, these components enable the efficient production of light in fluorescent tubes.
Property of a light that leads to formation of shadow?
They are light travels in a straight line and light cannot pass through opaque objects./ some light cannot pass through translucent objects.
What color does a green leaf appear to be in red light?
Black, obviously. The reason green leaves appear green is because when placed in white light, the leaf absorbs all the colors of the spectrum and reflects only green light. However, in red light, the leaf absorbs the red light but is unable to reflect any green light because there is no green to reflect. So, it appears black. Try watching green plants at night (or very low light conditions). That should give you a practical proof of the fact mentioned above.
How does a lemon power up a light bulb?
A lemon can power up a light bulb by acting as an electrolyte in a chemical reaction with the metals in the light bulb. When zinc and copper electrodes are placed in the lemon, a chemical reaction creates an electrical current that can power a small LED light bulb.

Would the amount of light increase decrease or remain the same when lamp is placed across a 120 V dc power line?
When a lamp is connected to a power supply the total amount of light increases.
When was Remain in Light created?
Remain in Light was created on -19-08-07.
What is the purpose of preheating in a fluorescent 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.
What is amoled capacitive touch screen?
An organic light emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emits light in response to an electric current. This layer of organic semiconductor material is situated between two electrodes. Generally, at least one of these electrodes is transparent.
What is the parts of fluorescent lamp and there functions?
A fluorescent lamp consists of a glass tube filled with mercury vapor and coated with phosphor. The tube is connected to electrodes at each end. When electricity is applied, the electrodes produce an arc, which excites the mercury vapor to produce ultraviolet light. The phosphor coating then converts the ultraviolet light into visible light.
Would a cork light up a light bulb?

Is it possible to light a bulb with raw peanuts?
Yes and no. If the peanuts are moist, not dried, they will act an electrolyte between two dissimilar metal electrodes - zinc and copper for instance - and form a cell that would power a low-volt lamp. The peanuts would be best if ground into a paste to ensure good contact and a continuous path between electrodes. The is also possible with something like a whole apple or potato as well, just push the electrodes in, but what is really powering the lamp are the chemical reactions at the electrodes.
How does a Carbon Arc Torch work?
A Carbon Arc Torch works by creating an electrical arc between two carbon electrodes. When current flows between the two electrodes, it ionizes the surrounding air, creating a high-temperature arc of light and heat. This intense heat can be used for welding, cutting, or melting metals.
