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?
