What else can I help you with?
Two lamps one with thick filament and one with a thin filament are connected in parallel to a battery . What explains why the lamp with the thicker filament burns more brightly?
The lamp with the thicker filament has a lower resistance compared to the one with the thin filament. According to Ohm's law, lower resistance allows more current to flow through the thicker filament when connected in parallel to the same voltage source. This increased current results in a higher power output (P = I²R), causing the lamp with the thicker filament to burn more brightly.
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 type of spectrum is produced by a filament lamp?
continuous emission
A lamp transforms electrical energy into what?
Mostly heat, but that heat causes a filament to glow, which makes light.
Which material is used for for filament in tungsten lamp?
i believe it is cadnium.
What size lamp shade harp should I use for my table lamp?
To determine the right size lamp shade harp for your table lamp, measure the height of the lamp base and add 1 inch for a standard fit.
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.
What part of the lamp converts electricity to light?
The light bulb or LED component of the lamp converts electricity into light through the process of electricity flowing through a filament or semiconductor material, which then emits photons, creating light.
What fuse should you use in a table lamp?
1amp 3 max depends on what rating lamp it is (or bulb).
What does a filament lamp do in a circuit?
A filament lamp produces light by converting electrical energy into heat and then light. It acts as a resistive load in the circuit, meaning it resists the flow of current and causes the filament to glow and produce light.
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.
Why Doesn't a lamp light up if the filament inside is broken?
If the filament inside a lamp is broken, it cannot conduct electricity properly, which is essential for generating light. The broken filament creates a gap in the circuit, preventing the flow of electricity needed to produce light. As a result, the lamp will not light up.

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 type of spectrum is produced by a filament lamp?
continuous emission
What are the parts of a lamp?
fifi eats the filament and turns it into a bernard
