Why wouldn't the lamp turn on?
Usual condition, no power source or lamp filament open.
What type of spectrum is produced by a filament lamp?
continuous emission
How does a table lamp differ from a bedside lamp?
You pull the string and it turns on, you pull it again and it turns off.
Which material is used for for filament in tungsten lamp?
i believe it is cadnium.
Why is the filament inside an electric lamp made very fine?
The filament is fine so that its electrical resistance can be quite high. It is also long, for the same reason. Usually it is coiled up to fit the length in the lamp. The heating effect of electric current is proportional to the current squared, time the resistance (I*I*R). Most of the effect is due to the current. The current through the filament must be limited to stop it melting. Adding resistance will do that. Taking resistance away increases heating. So, a low energy lamp has a very thin filament and a high energy lamp will have a thicker filament.
What part of the lamp converts electricity to light?
For a filament-type (incandescent) lamp, it's the filament.
Does a lamp with a thick filament draw more current or less current than a lamp with a thin filament?
A lamp with a thick filament will draw more current. What restricts the current flow in the filament is the resistance of the filament which increases as the temperature of the filament increases. A thin filament requires less energy to get heated up that a thick one so less current to achieve threshold resistance. Also a thick filament provides a broader path for current so there is less resistance per increase in degree centigrade. For these two (closely related but distinct) reasons it will require more current for the filament to get heated up to threshold resistance.
Which is more powerful a torch bulb or a mains filament lamp?
Mains filament
Why wouldn't the lamp turn on?
Usual condition, no power source or lamp filament open.
How do you Use filament in a sentence?
(Filament is a thread or thin wire.)Is the lamp unplugged or is the filament broken in the bulb?A silkworm's cocoon is made from a thin filament which can be twisted into thread.
What fuse should you use in a table lamp?
1amp 3 max depends on what rating lamp it is (or bulb).
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
What are the parts of a lamp?
fifi eats the filament and turns it into a bernard
What type of spectrum is produced by a filament lamp?
continuous emission
Why is there a curve and not a straight line in the graph for a filament lamp?
I had to answer this and found out that............ The line on the graph that represents the filament lamp is curved because the resistance of it increases with supplied voltage Hope this is alright for you :) x
Why should a metal table lamp always be earthed?
to ensure safety
