Because Copper is an excellent conductor of electricity it would take too much copper wire to make an element having sufficient resistance to fit into the small space provided in any normally-sized electric heater. For that reason heating elements must be made from metals which have a much higher electrical resistance than Copper. Special alloys of metals such as Iron, Cobalt, Nickel, Zinc and Manganese have been invented for this purpose.
Nichrome wire heats up faster than copper wire because nichrome has a higher resistivity than copper. This means that nichrome wire resists the flow of current more, causing it to generate more heat as current passes through it. Copper wire has lower resistivity, so it heats up more slowly.
No.
Copper is a very good conductor and is commonly used for wires because it has a very low resistance, which means the electricity will flow freely through it.
Nichrome has a very high resistance, so electricity flowing through it will slow down and lose energy, making it a bad conductor.

Nichrome conducts alot of current, so more heat can be generated.
Because it is EASY to use FAST to install gives up heat faster then steel or cast Iron and just about anyone above the age of 4 can solder it and it is light to handle
Copper is a very Good conductor, the current would simply follow through the copper without dissipating much energy (which means nothing would light up).
Because Nichrome has a high resistance and copper has a low resisitance.

Does copper conduct electricity better than nichrome?
Yes, copper is a better conductor of electricity compared to nichrome. Copper has a lower resistivity and higher conductivity than nichrome, which makes it more efficient at carrying electrical current. Nichrome is often used as a resistance wire in heating elements because of its high resistance to heat.
Why is nichrome used for heating element in a toaster?
A nichrome wire has high resistance and gets heated faster, saving electricity.
What alloy is nichrome made of?
nichrome alloy is made by mixing up of the metals nickel and chromium.
What colour flame do you get when you burn copper chloride?
Burning copper chloride produces a green flame due to the presence of copper ions in the compound. The green color is a result of specific energy transitions within the copper ions when they are heated.
How can copper be extracted using scrap iron nothing it doesnt work that way?
Copper cannot be extracted using scrap iron because iron is less reactive than copper in the reactivity series. To extract copper from its ore, a process called electrolysis or smelting is usually used. During smelting, the copper ore is heated with carbon to remove oxygen and extract the copper metal.
What has more resistance a nichrome wire or a copper wire?
A nichrome wire has more resistance than a copper wire. This is because nichrome is made of a nickel-chromium alloy that has higher resistivity compared to copper, which allows it to impede the flow of electricity more effectively.
Does copper conduct electricity better than nichrome?
Yes, copper is a better conductor of electricity compared to nichrome. Copper has a lower resistivity and higher conductivity than nichrome, which makes it more efficient at carrying electrical current. Nichrome is often used as a resistance wire in heating elements because of its high resistance to heat.
Why is nichrome used for heating element in a toaster?
A nichrome wire has high resistance and gets heated faster, saving electricity.
Why copper use at home rather than nichrome?
It might be newer than copper or less tested because this metal has been mixed with other metals such as iron
What happens to copper oxide when its heated?
if it is heated above 1200 degrees celsius than it melts
Why aluminum has high thermal expansion coefficient than Copper?
Aluminum has a higher thermal expansion coefficient than copper because its crystal structure allows for larger atomic movements when heated. This results in a greater expansion of aluminum compared to copper when exposed to heat. Additionally, aluminum has a lower density and stronger interatomic bonds, leading to a higher degree of expansion when heated.
Hydrogen over heated aluminium Nothing observed H over heated copper oxide Red glow spreads and leaves red powder that conducts electricity Why is H more or less active than Al or Cu?
The Pauling electronegativity of hydrogen is higher than the electronegativities of aluminium or copper.And copper is more reactive than aluminium.The red poweder obtained is copper as a metal.
When a bimetallic bar made of copper and iron is heated bar bends toward iron?
This is because copper expands more than iron when heated, causing the side with copper to elongate and bend towards the iron side. This phenomenon is known as thermal expansion and is utilized in devices like thermostats to control temperature.
When hydrogen gas passed over heated cupric oxide?
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
When cu and agno3 is heated what colour it gives and why?
It gives green color . Copper is more reactive than silver therefore it displaces silver from silver nitrate and forms silver + copper nitrate
What alloy is nichrome made of?
nichrome alloy is made by mixing up of the metals nickel and chromium.
Why does copper sulfate change mass when heated?
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
