ECT 122 Week 5 iLab 3

1.Determine the load voltage by deriving an equivalent circuit for the circuit below. Reduce the R1, R2, and R3 combination to a single equivalent resistance. Also, reduce R4 and RL1 to a single resistance.

2.Download the Multisim file “Ser_Par3” from Doc Sharing, Week 5. Run the simulation and verify the simulated load voltage matches the calculated value.

3.Modify the Multisim file to match the equivalent circuit you developed in problem #1 (Battery and two equivalent resistors). Run the simulation and compare the equivalent circuit’s results with the original circuit’s results. Are the results the same (YES/NO)? If no, determine why and correct it

4.Construct the original circuit above on the breadboard. Connect the circuit’s input to a DC power supply and set it to +10 V. Use a hand held DMM to adjust the supply to +10 V. Using the hand held DMM, measure the load voltage. Have the professor verify the circuit before applying power.

5.If using ELVIS, repeat step 4 using the ELVIS DMM instead of the hand held DMM. Have the professor verify the circuit before applying power.
