Question

Give one eg to show how the resistance depend on nature of material

Answer 1

Answer:

Explanation: If we take two similar wires of the same length and same diameter, one of copper metal and the other of nichrome alloy, we will find that the resistance of nichrome wire is about 60 times more than that of the copper wire. This shows that the resistance depends on the nature of the material of the conductor.

Answer 2

Answer:

If we take two similar wires of same length and same diameter, one of copper metal and other of nichrome alloy, we will find that the resistance of nichrome wire is about 60 times more than that of the copper wire. This shows that the resistance depends on the nature of material of the conductor.

Resistivity depends on temperature and nature of material. Resistance is the characteristic of a material which opposes the flow of electric current.
