Question

The resistances of commercially-available discrete resistors are restricted to particular sets. For example, the available values of resistors with tolerance are selections from the set multiplied by a power of ten from through . The set is: Thus, you can buy resistors with a nominal resistance of or , but not . Furthermore, the "tolerance" means that if you buy a resistor you can be sure that its resistance is between and . In this problem we need to choose resistors to make a current divider that meets a given specification. We are given an input curr
