Importance of resistor values


Recommended Posts


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.
