Loudness does not change with the change in :

A carbon and an aluminimum wire are connected in series.If the combination has resistance of 27 ohm at 0^(@)C ,what is the resistance of each wire at 0^(@)C so that the resistance of the combination does not change with temperature ? [alpha_(C ) = -0.5 xx 10^(-3)(.^@C)^(-1) and alpha_(A) = 4 xx 10^(-3)(.^@C)^-1] .
