Introduction
The purpose of this lab was to review the superposition and thevenin's
equivalent methods for solving a circuit, and circuit simulation using
LTspice.
Materials and Methods
Superposition and thevenin's equivalent calculations were done by hand, and the spice simulation circuits were built with code.
Results
Figure 1: Superposition hand calculations.
Figure 2: Voltage simulation values and spice code for superposition circuit.
Figure 3: Current simulation values in LTspice.
Figure 4: Thevenin's equivalent hand calculations.
Figure 5: Simulation results and spice code for the thevenin's equivalent circuit.
Discussion
The hand calculations and spice simulation values were the same for both the superposition and thevenin's equivalent circuits.
