Procedure:

*** This lab has to be implemented only in hardware (using NI myDAQ) ***

1. Analyze the circuit in the Figure 1 below to calculate the following values: V_B, V_E, I_E, V_C and V_CE.

2. Construct the circuit shown in Figure 1 below on the breadboard using the transistor and two resistors (R_C and R_E).

Figure 1

3. Using the jumper wires, screw driver and screw terminal connector, connect the board to NI MyDAQ Instrument Device.

4. Use channel +15V pin out on the NI myDAQ Instrument Device to provide the supply voltage (V_CC ). Use the Multimeter to measure the required voltages: V_B , V_E and V_C and currents: I_C and I_E .

5. Tabulate the data from step 1 and step 5.
