A carbon wire and a Nichrome wire are connected one after the other. If the combination has total resistance of 13.0 k at 20°C, what is the resistance of each wire (in Kohms) at 20°C so that the resistance of the combination does not change with temperature?
Nichrome resistivity = 1.5*10^-6 Ohm
Carbon resistivity = 3.5*10^-8 Ohm
