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. VCC was then increased until the current IC reached 10 mA. We found this voltage to be 9.2 Volts. The voltage
