The gases (or vacuum) inside electric bulbs is usually specific to what kind of bulb it is. It can be repaired, by separating the glass from the metal, replacing/correcting whatever is broken, and resealing it in an environment that will have only that specific gas (or vacuum) inside. It can be repaired, but it's at least the same effort/expense (probably more) as making a new bulb.
What else can I help you with?
Why it happens that when electric bulb heats up it does not glow?
When an electric bulb heats up, it can stop glowing if the filament inside breaks due to the extreme temperature. The filament in a light bulb glows when an electric current passes through it, but if it breaks, the circuit is disrupted and the bulb will not light up. This can also happen if the filament is damaged by vibration or stress.
What is a electric bulb in short?
a bulb is light bulb
Can you use a copper wire to make a filament of an electric bulb?
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!
Any three parts of an electric bulb?
Three parts of an electric bulb might include the filament, the actual bulb, and the base.
Which came first the telephone or the electric light bulb?
The electric light bulb came first but was patented later that the telephone was.
When electric bulb glows filament only glows and supporting metals do not why?
The supporting metals are insulated from the current path and current cannot flow.
What produces light in an electric bulb?
It depends on the type of bulb.
When did the bulb completed?
The electric light bulb was invented in 1879.
Why a lighted electric bulb connected to the main should not be touched?
do not touch alighted electric bulb conncted to the main
Why does electric bulb become dim when electric heater in parallel circuit is switched on?
The electric heater draws some of the electrical current in the circuit, which reduces the current available for the electric bulb. This leads to a decrease in the brightness of the bulb as it is receiving less power.
What does electric light bulb look like?
it look's like a mini light bulb and you usally use them in an electric circuit
What is the scientific name of electric bulb?
The scientific name for an electric bulb is incandescent light bulb, named after the process of incandescence which produces light through heating a filament.
