The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
The bulb glows because the electricity which is a form of energy which heats a wire inside of the bulb as it passes through. This gives a glow to the wire which is magnified by the curve of a bulb.
The bulb glows indicating that there is current flow. If there is any ammeter in the circuit, it reads when there is current flow in the circuit
Many metals will glow when heated to a high enough temperature. The metal (like in a light bulb filament) is heated up from the current passing through it. Most incandescent light bulbs use a tungsten filament. Appliance Heating elements (like in an electric oven), are usually composed of nickel and chromium. You can visually verify that Heating elements in ovens and toasters glow, as well.
Because the electrons from the Nylon cloth or silk are being passed to the light bulb

When a meteoroid passes through Earth's atmosphere it's traveling very fast. The friction of the air makes gets the surface so hot it begins to burn or glow red hot. This fire is what you see as it goes through the atmosphere. If it burns up completely it's called a meteor.
Most rocks and pebbles do not glow.
When current passes through the filaments, they get super hot and give out a glow. Mostly these filaments are made out of tungsten as they cool down fast.
Electricity through a thin wire (filament) makes it glow, which is prevented from burning through the wire by gas inside the bulb.
They produce light by using mercury vapor :D=======================Answer #2:Some (not many) pass electric current through mercury vapor, causing it to glow violet.Some pass electric current through sodium vapor, causing it to glow yellow.Some pass electric current through a thin wire, causing it to heat and glow ...a process is identical to that in every incandescent light bulb in your house.Some burn natural gas.
Electric current through a filament (thin spiral) of tungsten causes it to heat up enough to glow brightly.
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
The filament in the bulb has a high resistance to the flow of electricity. As electricity passes through it, the filament heats up and begins to glow, giving off the visible light you see.
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
There must be a current through the bulb in order for it to glow.
This is usually done by passing an electrical current through the wire.
you have to need IC 3 ,bulb
