Great John and good luck ! The military stuck me in an electronics school as the beginning of a course in radar systems repair. That was March 1953. I'm still trying to understand Ohm's Law ! Murphy's Law I have proven over and over but Ohm's is still a puzzlement. I think Ohm and Murphy should have gotten together and worked out some sort of compromise before they published. We'd all be less for wear and might even have done something constructive by now. Here's another link........ this is a good place to start your course of instruction..........
