A resistor is to have a constant resistance of 30.0 S, independent of temperature. For this, an aluminum resistor with resistance R01 at 0 °C is used in series with a carbon resistor with resistance R02 at 0 °C. Evaluate R01 and R02, given that a1 = 3.9 X 10^-3 °C-1 for aluminum and a2 = —0.50 X 10^-3 °C-1 for carbon.

Solution:
A resistor is to have a constant resistance of 30.0 S, independent of temperatur
