Hello. As the title says, I need some help in getting a transistor to amplify a current. I have a TIP120, whose DC gain is specified as 1000. I am applying a positive voltage of about 0.6 V to the base. The current is around 10 μA. I have the positive side of a AA cell connected to the collector. The emittor connects to the negative side of the "battery", and to the negative of my 0.6 V signal being applied to the base. Why am I not reading around 10 mA from the battery? Turning off the base voltage causes the reading to become zero. Still, when the signal is applied, I am only reading 20 to 30 μA.
