Why is much less heat generated in long electric cables than in filaments of electric bulbs?
Heat generated in electric cables is due to resistance, which depends on the material and length of the cable. Longer cables have higher resistance but lower current compared to bulbs, which have a constant high current running through a filament, resulting in more heat generation. Additionally, bulbs are designed to convert more electrical energy into heat for illumination, whereas cables are designed to minimize energy loss.

What is the metal in domestic light bulbs?
The metal used in domestic light bulbs is typically tungsten. Tungsten has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it, making it ideal for use in light bulb filaments.
What element are used in light bulbs as a filaments?
Tungsten is commonly used as a filament in light bulbs due to its high melting point and resistance to heat. It can be shaped into a thin wire that glows when an electric current passes through it, producing light.
What two materials did Edison use to make filaments?
Edison used carbonized bamboo and then switched to carbonized cotton threads as materials for his early filaments in his incandescent light bulbs.
What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
The element used in light bulbs filaments?
Tungsten is the element most commonly used in light bulb filaments due to its high melting point and ability to produce light efficiently when heated.
What element is found in filaments of electric bulbs?
Tungsten is the main one. There may be others.
What metal use the filaments in light bulbs?
Tungsten is used in filaments of light bulbs.
What is the metal in domestic light bulbs?
The metal used in domestic light bulbs is typically tungsten. Tungsten has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it, making it ideal for use in light bulb filaments.
Greyish white element used in lamp filaments?
Tungsten is a greyish white element commonly used in lamp filaments. It has a high melting point and can withstand the high temperatures generated when electricity passes through it, making it ideal for use in light bulbs.
What element are used in light bulbs as a filaments?
Tungsten is commonly used as a filament in light bulbs due to its high melting point and resistance to heat. It can be shaped into a thin wire that glows when an electric current passes through it, producing light.
Why is a copper wire not used to make filaments of electric bulbs?
Because the filament is in effect a resistor. Copper is too good a conductor to provide resistance to the current, and would simply allow the current to complete the circuit. The light is generated by the filament glowing as it heats up in resistance to the current. Tungsten is a much better resistor.
Do uranium use in light bulb?
Uranium is not commonly used in light bulbs. Light bulbs typically use tungsten filaments to produce light when an electric current passes through them. Uranium is more commonly used in nuclear reactors to generate electricity.
Which element is used in the filaments of household light bulbs?
usually tungsten
What element makes up the filaments in light bulbs?
It is usually Tungsten.
How many filaments exist in a light bulb?
Most incandescent bulbs have one filament. Some halogen bulbs working on 240 v have two filaments in series, which must be to simplify manufacture of bulbs being made for 120 v and 240 v in the same factory.
Invented toilet system for railroad cars and electric lamppublished book that became guide for lighting engineers?
Lewis Howard Latimer invented a toilet system for railroad cars. He also invented an electric lamp using carbon filaments in light bulbs.
Element used in light bulb filament?
That depends on the bulb, and the time frame. The first bulbs had carbon filaments. Certain bulbs used in control devices have iridium filaments. Modern grocery store incandescent bulbs have tungsten filaments.Tungsten, because of its very high melting point.
