Write name of two metals which have low melting point.

The resistance R of a conducting wire depends on its material , length l and area of cross section A. The resistivity of the material of the wire is rho=(RA)/t the value of rho is for different materials .It is very low for conducting materials like metals,Besides, the resistance of a conductor also depends on its temperature. IF the resistance of a conductor is R_0 at 0^@C and R_1 at t^@C , then R_1=R_0(1+at) where a is called the temperature coefficient of resistance. The resistance increases with temperature for metallic conductors but decreases for graphite,a few metal alloys,and for semiconductors like silicon and germanium. The temperature coefficient of resistance of a semiconductor is
