WHY THE BULB LIGHTED WHEN THE TWO ELECTRODES CONTACT?
When the two electrodes contact, it completes the circuit, allowing the current to flow from one electrode to the other through the bulb. The current passing through the filament of the bulb causes it to heat up and emit light, resulting in the bulb lighting up.
Where would you put a convex lens to throw an enlarged image of lighted bulb on a screen?
You would place the convex lens between the lighted bulb and the screen, with the lighted bulb positioned beyond the lens's focal length. This arrangement will create an enlarged image of the lighted bulb on the screen due to the converging properties of the convex lens.
What form of energy conversion will take place when a bulb is lighted up?
When a bulb is lighted up, electrical energy is converted into light energy and heat energy. The electrical energy flows through the filament in the bulb, causing it to glow and emit light while also generating heat.
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.
Why did the flashlight light?
The flashlight lighted up because there is a source of electricity, typically provided by batteries, that powers the bulb to emit light when the switch is turned on.

What is the meaning of series circuit?
if the one bulb is not lighted the all is no lighted

When was the first electric bulb was lighted in India?
in bangalore
What does a lighted bulb indicates?
inspiration, or a bright idea
What is cold resistance?
That is e.g. the resistance of a cold bulb before the bulb is lighted and heats up.
What is energy transforms in a lighted bulb?
Chemical to radiant(light:)
When the switch is off why does your CFL bulb pulse when used in light fixture controlled by a 3 way lighted switch?
The bulb "pulses" because the circuit is not completely off. If the CF bulb is pulsing or flashing, it means that there is some kind of feedback loop providing at least some voltage to the bulb. Often lighted switches use the filament resistance to provide voltage to the internal bulb. Get rid of the lighted switch.
Why a lighted electric bulb connected to the main should not be touched?
do not touch alighted electric bulb conncted to the main
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 many electrodes are in a bulb?
2. one on the side and one on the very bottom
Can photosynthesis take place in the presence of a lighted bulb?
Yes,it provides red and blue light.
