this seems to be the best place for answers on everything so here goes. I'm trying to have a little electrical fun with my dashboard lights and I have some questions about resistors. If you run batteries in series you get more voltage if you run in parallel you get more current. What happens to when you run resistors in parallel or series? does parallel just allow them to handle more current? What's the deal with the wattages on resistors? is that the max wattage you can run through one? I'm planning on replacing my dash bulbs with much brighter LEDs. I need resistors to step down the voltage of the power source. Thanks for the help.
