Which has high resistance Nichrome or copper?
Suppose,we have two wires of equal length and the same cross sectional,one made up of nichrome and the other made up of copper metal. Then, nichrome wire will have more resistance than the copper wire.
Which is thicker Nichrome or copper?
Nichrome is thicker than copper because it has higher resistivity than copper. Alloys are used for the given purpose because of their high resistivity and appropriate low melting point. Nichrome is thicker than copper because it has higher resistivity than copper.
Which wire is the best conductor of electricity between Nichrome and copper?
Copper was the best conductor because it had more free electrons. The electrons in the copper wire came up against fewer resistances while flowing in the current, than in the nichrome wire. Resistance is the result of energy loss as heat.
Which has more resistance copper or tungsten?
Answer. Copper is better conductor than tungsten. Tungsten has high resistance. Hence it is used in making of filament of bulb.
Why tungsten wire produces more heat than copper?
1. Its melting point is lower than tungsten and at high temperature the copper will melt. Resistivity of tungsten is higher than copper. If we use a thick tungsten wire in the electric bulb , then the resistance will get reduced and to achieve the requisite heat, more energy will be spent.
Why copper is not used in bulb?
Copper wire cannot be used to create an electrical bulb filament, because copper wire has very low resistance. Therefore, the light does not shine until the current is removed.
What will happen if a thick tungsten wire is used in an electric bulb?
The bulb will not function properly. 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.
Why copper wire Cannot be used as a filament in an electric bulb?
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!
Can you use a copper wire to the filament of an electric bulb?
copper wire cannot be used as a filament in an electric bulb.
Why does the filament in a light bulb offer much more resistance than copper wire?
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.
