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.

So,what is inside the nichrome wire that causes them to have more resistance than copper even if the wires are of same length and same cross sectional area?

I think the nichrome wire has less free electrons in their atoms.So,the number of collisions increase and it's resistance increase.PLease correct me if i am wrong.

Kindly tell me what is the difference between copper and nichrome which makes nichrome to have more resistance than copper even if the wires are of same length and same cross sectional area?

I am sorry for my bad English!

English is not my first language.
