From what I've read about transistors, I thought that I could find the hfe value in the data sheet, then apply a current to base and have the emmitter-collector throughput at a level of base*hfe. It sounded simple, and I was going to have a few different resistors for controlling base current, selected by a switch.
Well, I was confused off the bat, when looking at the data sheet. There was no 'nominal hfe'. There was a max hfe, a minimum hfe, and they were very different values. So how can I do what I wanted to do... know the output current via the base current? It sounds like I'm missing a general principle.
Thanks
