In a common Emitter configuration, and the circuit is acting as switch; Let us say you design the circuit to provide 100 ma at the collector.
If I plug in a led ( 20 ma) with NO resistor to protect it; Will the transistor Ic provide ONLY 20 ma or I loose the led ?????
There is a lot of talk about transistor dynamic resistors and "early voltage" that I do not understand.
I am hoping for a circuit that can provide such "Intelligent" response that performs according to the load.
