In pnp type, the transistor consists of two p … WebAs said earlier, we will operate our NPN transistors in the saturation region. This means that the collector current will not be dependent on the base current anymore - it reaches a maximum set only by the collector resistance. I will use 5V in most of my circuits but we will vary that around. I did not measure the forward voltage of the LEDs ...
