The wire which is used to convert electrical heater into heat energy in any heating devices is called heating element. Nichrome wire is used as heating element in electric heater.
Which wire is used in electric heater and why?
Hence, the nichrome wire is used as a heating element because it has high specific resistance. Thus, the correct option is C. Note: A nichrome wire is used as a heating element because of its high melting point and high resistivity (low conductivity) also.
Which heating element is used in heater and why?
A nichrome wire is used as a heating element for a room heater because the resistivity of nichrome is high and increase in its value with increase in temperature is high.
Which wire is good for heater?
Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures. When used as a heating element, it is usually wound into coils.
Why is nichrome wire used in electric heater?
Because of its low cost of manufacture, strength, ductility, resistance to oxidation, stability at high temperatures, and resistance to the flow of electrons, nichrome is widely used in electric heating elements in applications such as hair dryers and heat guns.
What is heater wire?
Heater ProductsSingle-line Type Heater Wires
Safe and reliable heater wires combining temperature detection with safety and protection elements, which can be used for a wide range of warming applications.
What is called a coil of wire of electric heater?
The correct answer is Element. An electric room heater or an electric heater used for cooking contains a coil of wire. The coil of wire used in electric heaters is called an element. … The coil of the electric heater is made up of nichrome. Nichrome consists of 80% nickel, 20% chromium.
What are the features of heating element?
(i) It should have a high resistance so that a major amount of electric energy is converted into heat energy. (ii) It should not get oxidised easily up to a temperature of 1000°C. (iii) It should have a high melting point and a low thermal Expansion so that it does not get loosened on getting heated.
What is a heating element made of?
Metal heating elements generally are made from nichrome, which is composed of 80% nickel and 20% chromium. Nichrome 80/20 make great heating elements because the material yields a pretty high resistance.
Is used in electric heater?
An electric heater is an electrical device that converts an electric current into heat. … Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators.
What has Nichrome wire in it?
Nichrome wire is commonly used in heating applications for tools and appliances, hot-wire foam cutters, vaping and electronic cigarette coils. It is used in items found in our homes, for example, your toaster may contain nickel chrome heating wire.
Which wire is used in fuse?
Which material is generally used in a fuse wire? Answer: An alloy of lead and tin as it has a low melting point and a very high resistance.
What can I use instead of Nichrome wire?
Nichrome is good, steel or stainless steel should also work ok and may be preferred if you need less heat and more strength.
