Part Two: Simulation
Using LTSplice, simulate the circuit in figure 2, comparing your simulated results with your hand
calculations.
Experiment
In Lab Measurements
Build the circuit pictured in figure 2, measuring the voltages at each node and the current
flowing through each resistor. Compare your results to the hand calculations and simulated
results you obtained from the Pre-Lab.
