1) The resistances of commercially-available discrete resistors are restricted to particular sets. For example, the available values of resistors with 10% tolerance are selections from the E12 set multiplied by a power of ten from 100 through 10s. The E12 set is: E12-10,12, 15, 18,22,27,33,39,47,56,68, 82) Thus, you can buy 10% resistors with a nominal resistance of 3300 or 33M. but not 350n. Furthermore, the tolerance a 10%...
