Hi.. can someone answer me this question? I have a question in my paper which ask me to calculate some resistor values for some circuit design. After calculating, u get some random answer and it ask you for easily available component( store component value). For e.g. "1.09k ohm" will be "1K ohm" etc... How can i or is there a way to know/memorize what values of the resistors value are commercially and easily available? I hope someone understand me and give me an answer soon. Thanks a lot!
