Materials and Equipment:
Materials:
• Hardware Parts (In the Toolbox):
An NPN transistor: 2N3904
Two resistors: 10 kΩ and 3.6 kΩ
Jumper wires
Equipment:
• Hardware Equipment:
Breadboard
NI myDAQ Instrument device
Screw Driver
Screw Terminal connector
USB Cable
Multimeter probes
Oscilloscope, Multimeter and Function generator from NI ELVISmx Intrument Launcher
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: VE, IE, VRC, VC, VCE. Make sure to include 20% tolerance for each resistor in the calculations.
2. Construct the circuit shown in Figure 1 below on the breadboard using the transistor and two resistors (RCand RE).
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 (VCC) and channel AO0 to provide the base voltage (VBB). Make sure that this voltage is peak-to-peak. Use channel AI0 to measure the required voltages using the oscilloscope.
Figure 1
5 .Using the function generator from NI ELVISmx Instrument Launcher, provide the input voltage VBB to the circuit.
6. Use the oscilloscope to measure the voltages: VE, VRC, VC, VCE.
7. Now, using multimeter with the probes, measure the required voltages: VE, VRC, VC, VCE and currents: IC and IE.
8. Tabulate the values obtained in step 1 and 7.

Review questions:
1. Compare the calculated and measured values in the table and analyze the performance of the transistor.
2. Discuss whether the values are the same or different. If they are different, provide the reasoning and explain how to reduce this difference between calculated and measured values.
3. Explain what happens when the transistor changes to a PNP transistor. How does the change in the transistor effect the current and voltage in the circuit?
Deliverables:
• Analysis of the circuit and calculations of voltages: VE, VRC, VC, VCE and currents: IC and IE.
• Place your student ID card on the breadboard and take a picture of the circuit board and pin out on the NI myDAQ Instrument Device.
• Take screenshots of the measurements obtained from function generator and Multimeter on the NI ELVISmx Instrument Launcher on your screen.
