Current amplification of a bipolar junction transistor.Lessons In Electric Circuits, Volume 3, chapter 4: “ Bipolar Junction Transistors” Neither is the particular light emitting diode (LED) selected. Resistor values are not critical for this experiment. One light-emitting diode (Radio Shack catalog # 276-026 or equivalent).One NPN transistor-models 2N2222 or 2N3403 recommended (Radio Shack catalog # 276-1617 is a package of fifteen NPN transistors ideal for this and other experiments).
