The constant resistance of a resistor is 3030 ohms, independent of the temperature. The resistor is made up of an aluminum resistor with resistance R1R1 at 0C0C in series with a carbon resistor with resistance R2R2 at 0C0C. Evaluate R1R1 and R2R2, temperature coefficient for aluminum and carbon are 3.9×10−3C−13.9×10−3C−1 and −0.5 0×10−3C−1−0.50×10−3C−1.​
