Why is nichrome better than copper




















Can we use copper wire instead of Nichrome in meter bridge? Copper cannot be used as a meter bridge wire because it has low resistance and high-temperature coefficient of resistivity. Nichrome is characterised by a silver-grey colour and has a high resistance to electrical flow and heat.

It is also very resistant to corrosion and wear, is very durable and has a very high melting point at around 1,oC. Its resistance to oxidation make nichrome a popular material for use in heating elements.

Nichrome wire, an alloy of nickel and chromium, and often iron or other elements is good for making heaters but not lamps. At rated voltages, nichrome will glow orange-red, not the bright white that is needed for illumination. If you increase the voltage to get a brighter color, the nichrome will burn open melt. 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.

The material used for making fuse element has a low melting point such as tin, lead, or zinc. A low melting point is, however, available with a high specific resistance metal shown in the table below.

The material mainly used for fuse element are tin, lead, silver, copper, zinc, aluminum, and an alloy of lead and tin. Havells flexible cables and wires are best in class in the flexible cables category and also the range includes flame retardant low smoke cables, multicore round cables, coaxial cables and heat resistant flame retardant cables.

Table of Contents. This is because the resistance of a thick wire is less than that of a thin wire. The filament should be having a high resistance in order to glow, which will definitely get reduced if we use a thicker wire. No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance.

Therefore, the bulb will not glow if current is passed. It would also melt — the filament has to be white-hot to be any use! When electricity flows through an object, the electrical resistance of the object limits the amount of electricity that can flow through it. But very quickly, a ton of heat is produced, which makes the filament much more conductive than it was, and the amount of current flowing drops off.
