The resistances of commerciallyavailable 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 105. 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 330Ω or 33kΩ, but not 350Ω. Furthermore, the "tolerance" means that if you buy a 10% 390Ω resistor you can be sure that its resistance is between 351Ω and 429Ω.
In this problem we need to choose 10% resistors to make a current divi

Best ResponseYou've already chosen the best response.0general resistors a R(1+x) x is the tolerance The ones mentioned come with x = .05, .1, .2 There are others available with x = .01, generally metal film, some come standard and some not There's all available x = .001 but have less standard range Aside from resistor tolerance there is also associated temperature coefficient. To find these and other available there's a number a electronic catalogs either through mail or online, one source is DigtKey
