Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
What is the difference between a filament of a bulb and an element of an electric heater?
The heater element is thicker wire, and has lower resistance. It still has enough resistance to glow red hot (producing heat) but does not glow white-hot and very brightly like a light bulb filament. Also, it lasts almost indeifnitely. whereas the light bulb filament has a finite life - it will "burn out" sooner or later.
When wire is thicker its resistance is?
When a wire is made thicker it's resistance decreases.
What will happen if you use a thick tungsten wire in the electric bulb?
The heat and light of the filament in an incandescent bulb is simply the powerdissipated by the resistance of the filament. The power dissipated by a resistoris simply (current through it)2 times (its resistance). A thicker wire used as thefilament has less resistance, which means that for any given current throughit, it dissipates less power than a thinner filament would.In simplest terms, the thicker the filament is, the more juice you must jamthrough it to make it glow.Another AnswerIncreasing the thickness of a tungsten wire will increase its cross-sectional area which will reduce its resistance. The filament of a higher-wattage lamp has a lowerresistance than the filament of a lower-wattage lamp, This is so because the power of a lamp filament is determined by dividing the square of the voltage by its resistance -the lower the resistance, the higher the power output. So reducing the resistance (by increasing its thickness) of the tungsten filament will increase its power output and, therefore, increase its brightness.
How does the thickness of wire affect the resistance?
A thicker wire has less resistance than a thinner wire.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
What filament is thicker a 60-W or a 100-W bulb of the same length?
I'm pretty sure the filament of a 60-W bulb is thicker, since there is less resistance through a thicker filament, so less light and heat would be generated.
There are three bulbs of 600W 100W and 200W which bulb has thickest filament?
600w - the thicker filament has a lower resistance, which leads to a higher current and thus higher wattage
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.

When a wire is made thicker it's resistance decreases.
What happens to the muscle tissue in response to resistance training?
the muscle tissue breaks and then grows back stronger and thicker
A thicker resistance wire produces more heat?
I'm not sure what you mean by "thicker resistance" wire? The thicker or more diameter of a wire the less resistance it has. A larger diameter wire would produce less heat. More resistance would produce more heat.

Will increasing the conductor thickness increase resistance?
No. A thicker conductor will lower resistance.
What tends to be thicker and more resistance to flow?
Blood
