I just took measurements with a 82K led load, and a 5K input resistor. What I find is that Vbe is still 0.7V; the base current Ib however is 550uA when Ic is 15uA.
So the transistor doesn't work as a current amplifier at all anymore, quite the contrary. Is it ok? How do I know that for some loads Ib will not go over my 10mA limit?
