Explanation: It is given that two wires of A and B with circular cross section made up of same material with equal length such that, R is the resistance . As material and length are same, there resistivity will be same. So, the ratio of the ratio of radius of wire A to that of B isWire material. Solar wires can also be classified based on the conductor material used. For domestic and commercial installations, the use of aluminum and copper solar wires is common. Copper wire has superior conductivity compared to aluminum. The same copper solar wire size carries more current than aluminum.

All four materials have a high conductivity, silver having the highest. All four can easily be drawn into wires and have a high tensile strength, though not as high as copper. The obvious disadvantage of gold and silver is the cost, but silver and gold wires are used for special applications, such as speaker wires.According to this law, the resistance value of two-wire made up of different materials is different although they are the same in their length and cross-sectional areas. From all these laws the resistance value of a conductor with length L and cross-sectional area A can be derived as. R ∝ L/A

The conductor material is so chosen to have high conductivity, low temperature coefficient of resistance, good adhesion to substrate and etching, etc. Aluminum, copper, gold, and silver are mainly used as conductor materials.
