abador Posted March 10, 2011 Report Share Posted March 10, 2011 Hey, I don't have a large variety of resistors so I have used what I have. I have a 10 ohm, 20 ohm, 33 ohm, 1 Kohm and a 10 Kohm. Is this a good starting point? How close should the resistor value be to the value stated in a schematic? Quote Link to comment Share on other sites More sharing options...
Hero999 Posted March 10, 2011 Report Share Posted March 10, 2011 It depends on what the resistor does.If it's something like a a current limiting resistor in series with an LED or transistor's base then it's not critical so you can go 10% either way but if it's in a potential divider which determines the output voltage of a regulator, such as the LM317, it's more critical.If you don't understand the schematic then use the exact value or seek advice from someone who does. Anyway I think at least having a basic understanding of a schematic should be a prerequisite for building it. Quote Link to comment Share on other sites More sharing options...
