Review of Superposition, Thevenin's Equivalent Circuit and LTSpice

Introduction:
In this lab we reviewed Superposition, Thevenin's and how to use LTSpice

Materials and Methods:
In this Lab we used the computer program LTSpice to gather simulation results. We used both superposition and Thevein's methods to complete circuit analysis.

Results:

Task 1: Superposition



Figure 1: Shows the code used in LTSpice to generate the simulation

Figure 2: Shows the results from the simulation

Figure 3: Hand Calculation for the same circuit to compare.

Task 2: Thevenin Equivalent


Figure 4: LTSpice code and results used to simulate the circuit.


Figure 5: Adjusted Code to run the simulation in LTSpice to get the proper results.

Figure 6: Showing the simulations time difference.


Figure 7: Hand Calculated results.


5. Discussion
As seen above the hand calculation results are really close to the simulation results. This shows that each step was done correctly and we are able to confirm all the results. The Lab was able to be successfully completed.
