My guess (it's been ages since I dabbled in electronics...), is that the resistor is there to prevent the destruction of the power supply in case in a short circuit in its load. In other words, it gives an upper limit to the current that you can draw out of the power supply. But I may be wrong... -- Nadav Har'El | Wednesday, Jul 14 2010, 3 Av 5770 [email protected] |----------------------------------------- Phone +972-523-790466, ICQ 13349191 |Lottery: A tax on people who are bad at http://nadav.harel.org.il |math. _______________________________________________ Linux-il mailing list [email protected] http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
