Here's another one that's had me scratching my head from time to time.
Suppose I want to put several of some kind of semiconductor in parallel. I know I need to put a resistor in series with each device to ensure the current through each is roughly equal, but question is, how do you work out what value of resistor you need? Is it based on how much inequality you are prepared to tolerate? Or is there something more empirical to go with?
Thanks in advance
