I am struggling with teaching myself some basic electronics. I have been reading up on transistors and I am struggling to get them to work the way I think they should (which is most likely wrong!).
In the attached diagram can anyone let me know why the NPN get so hot it almost sticks to my finger!? The current is low, around 40mA but this transistor is a 2W which should be fine for this voltage and LED.
Am I doing something incredibly stupid!?
