ECT 122 Week 7 iLab 1

1. What is Thevenin’s theorem? What purpose does it serve?

2. What is V_TH? How is it measured? 

3. What is R_TH? How is it measured? 

4. Given the circuit below, determine the Thevenin equivalent voltage and resistance.

5. Download the Multisim file “Thevenin1” from Doc Sharing, Week 7. Run the simulation and verify that the simulated results are the same as the calculated values. Were the values the same? Yes/No. If No, why not?

6. Construct the Thevenin equivalent circuit for the circuit above on a breadboard. Connect the circuit’s input to the power supply and set it to +10 V. Use the handheld DMM to adjust the supply to +10 V. Measure the load voltage using the DMM. Remember that to measure current, the DMM must be in series with the resistor. Have the professor verify the circuit before applying power.
