When I built my round house and was putting lights in it, I discovered that the more LED's I put in series, the more power they needed to light them all. I could get a max of 3 2mm LED's in series behind a 1K resistor and still have them lit. If I ran 4, they wouldn't light, and if I ran just 2 they were much brighter.
So, following this logic, if I added, say, 10 LED's to a series, would I be able to light them all behind a 0.2k resistor? Or 20 with no resistor at all? (No real math went into these calculations - just making the numbers up.)
Or would the lead LED just get toasted by the extra voltage leading to a cascade of failures down the series?
