A temperature-stable resistor is made by connecting a resistor made of silicon in series with one made of iron. If the required total resistance is 900 in a wide temperature range around 20°C, what should be the resistances of the two resistors? The temperature coefficients of the resistivities for iron and silicon are: Resistance of the silicon resistor at 20°C : S Enter 0 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] iron 5.0× 10-³ K-1 silicon=-75× 10-³ K-1 -
