Purpose: The goal of this experiment was to familiarize students with the Bipolar Junction Transistor and to understand the concepts between base and collector currents. Experiment: Common-Emitter Configuration: The first portion of the experiment was to setup the circuit below using R1 and R2 values of 68K ohms and 100 K ohms respectively. Figure Common-Emitter Circuit Configuration We created an open-circuit for the base connecting by removing R1 (meaning the base current is zero), raised VCC to 16 V and measured the voltage across R2 and calculated VCE accordingly. The tabulated results can be seen in the table below: VCE (V) VR2 (V) Calculated Ic (mA) 8.96 7.04 0.0704 8.96 5.04 0.0504 8.97 3.03 0.0303 8.97 1.03 0.0103 8 0.00015 0.0000015 6 0.00006 0.0000006 4 0.00003 0.0000003 3 0.000025 0.00000025 2 0.00002 0.0000002 1 0.00001 0.0000001 Table Calculated Values from Open Circuit In the next portion of the experiment we replaced R1and switched R2 with a 100 ohm resistor. VBB was adjusted so that the base current was IB= 10 μA. We set VBB to 1.2275V and found VBE to be 0.5475 Volts.
