why doesn't the resistor on the collector limit the current going collector to emitter? I have collector hooked up to +5v , emitter to ground and base current is 3uA . The collector current is .6mA with no resistor or with 4600 ohm resistor it doesn't make a difference. I can't find any information about it

The resistor will limit the current, but in this case it will limit it to about 1.1mA

The transistor is amplifying the base current just like it should (with a gain of about 200)
